Prologue: First Contact
Dock Shuttle at Luriam Space Station
After the opening cutscene, fly toward the colony ahead and to the right. Follow the trail of blue lights when you find them, and you will land in the station.
Meet Ethan in Hotel Lounge
Go through either of the 2 doors to the left, then continue through another door into a large open area. Go straight ahead and you will eventually find your brother standing by himself.
Knock Out Angry Marines
Fight the group of marines with the help of your brother; if your health starts getting low, run away and let it recover. It is easiest just to take on 1 enemy at a time.
Head along the corridor and through a door, then down some stairs. Go right as indicated, then around the top of the training room and down some stairs. Head through the 2 doors opened for you by guards, and enter the training room. For your first drills, practice targeting and shooting. When you are done, use the nearby elevator to get to the control room of the training simulator. After the introduction, go along either corridor and get some weapons from inside the arena. Fight against several groups of enemies, using the medical stations as needed.
When Ready, Proceed Back to Instructor
You can stay in the simulator and train for as long as you want. When you are done, return to the control room.
Stun all Marines
Grab 2 stunners before re-entering the arena. Stun the 4 enemies that appear to complete this round.
Make sure you have a stunner and use this to take out Bud. If you stun him, the marines will help you more during the upcoming fights; if you kill him, they won't.
Follow Ethan to Hangar and Enter Ship
Use the elevator, then follow Ethan to the ship.
Chapter 1: Hostile Negotiation
Get Ethan Away from Crash Site
Head through the door straight ahead into the next room.

Evade Seekers and Get Ethan to Escape Pod
Just make your way forward through several rooms until you reach the escape pod; don't worry about shooting the Seekers, just let Ethan and the marines take care of them.
Find a Way Out of Luriam Military Sector
Get some assault rifles from the cabinet on the wall, then go through the small door on the right.

Defend Marines Until They Open Door
Take out several waves of Seekers coming through the back and right walls, until the door on the left is opened.
Find a Way Into Luriam Science Sector

Find a Way to Upper Science Labs
Kill the few remaining Seekers that are hiding behind shelter in the room ahead. Continue through the door at the end into a lecture room. Make your way down, around the front, and up the other side of this room. Kill some more Seekers through the next doorway, then go up the ramp and around the ledge. Make it to the next room to see an explosion from the right, then enter the second room and jump through a hole blasted in its left side. Kill a Seeker attacking a scientist, then make you way through to a larger office room.
Defend Elite Soldiers While They Open Door
Just stay in this room and defend while multiple waves of Seekers come from all directions. The door ahead will eventually open.
Go through the door and up the ramp, then use the elevator. Press forward up one of the ramps on the left side and you will discover Olivia. Go back down and use the medical station, then approach the door with the yellow indicator above it to meet your first enemy boss.
Defeat Seeker General
The easiest way to beat this boss is by shooting first, then when he pulls out his shield, throw grenades.
Escort Olivia Back to Escape Pod
After the boss is dead, Olivia will rejoin you. Head through the door towards the elevator.
Escort Olivia to Lower Science Labs
Make your way back down in the elevator, then through the previous rooms - don't worry you cannot hurt Olivia while you are escorting her.
Find a Way Out of Luriam Science Sector
Go through the door at the bottom of this area. Go through the 3rd door on the left, then down a ramp on the right. Use the medical station here, then go through either door and turn right. Find another elevator at the far end of the hallway and use it to go down. Kill a group of Seekers here, then follow the corridors to a door at the end.
Escort Olivia to Hangar Lift
Go through the red doors and help the sims in a battle, then take the corridor on the left and help out some marines. Go down and then up the opposite ramp, then use an elevator.
Escort Olivia Back to Escape Pod
Turn left at the top and follow the ramp to the top, then head through the door on the left and follow the passages. You now need to choose to take either Ethan or Olivia with you to the escape pod - this will affect multiple future cutscenes as well as the appearance of the final boss.
Carry Olivia/Ethan to Escape Pod
After selecting who you will save, take them to the escape pod.
Chapter 2: Surface Tension
Run forward and slightly to the left to find a few building, killing a few enemies along the way. Turn left from the massive blue tunnel entrance and you will find the Scythe. Jump in.

Drive back towards your companion, trying to mow down the remaining enemies as you go.
Drive Scythe to Tunnel Entrance
Now turn around and drive back to the tunnel entrance, which will slowly open up as you approach.
Drive Scythe Through Western Canyon
Drive straight ahead until you see the broken bridge, then turn left and follow this canyon around slightly more to the left.
Make Your Way Towards Bahr Han City
Continue straight, then turn right when instructed. Just as you reach the edge of the canyon, use your turbo to successfully jump over the gap; if you don't make it, turn right at the base of the canyon and you will find a path back up to try again. Once over the other side, turn left when instructed and jump over another canyon. Now keep following the path for quite a long way - you can either crash into or ignore the enemies along here.
Enter Bahr Han City
Turn left when instructed, then find a large road and follow it into a tunnel.
Enter Bahr Han City
Continue along the tunnel until you reach a broken bridge - fall into the canal on the left side.

Find a Way Out of Sewers
Drive straight ahead and you will end up in water again. Turn right and follow this path until a hole is blown in the left wall. Get out of the Scythe now and climb through the opening. Go up in the elevator.
Proceed to Platform Lift
Take either doorway ahead and continue to reach an outdoor area. When you reach the fork, explore the right to find a rocket launcher, then take the left path. Continue over the broken street and head right. Follow this area to find a large street that ramps upwards, then fall down the other side.
Defend the Area Until the Elevator Arrives
The easiest way to survive this section is just to run straight ahead for the elevator, as the enemies will otherwise keep re-spawning. Turn around and defend yourself here until elevator arrives.
Continue to Platform Lift
Turn around and step on the lift - it will automatically descend.
Chapter 3: Extinction Agenda

Defend Area Until Marine Unlocks Door
Hop in the nearby turret and use it to take out 3 Seeker ships as well as a group of Seekers on foot.
Find a Way Back to Upper Launch Deck
As soon as the door behind you is open, leave the turret and go through. Use the medical station, then use the elevator. You can just dodge the enemies in this area as you make your way to the far end of the platform. Go through the door on the left and descend in another elevator.
Defeat Seeker Shock Troops
Kill the Seekers and the 2 Shock Troops (safest to use grenades or rocket launchers).
Proceed to Launch Deck
The door at the far right should now be open. Head through and kill a whole lot of Seekers in a long hallway, then use the elevator at the end.
Proceed to Western Lift
Go forward into a massive open area. There are Seeker ships, Shock Troops and a whole lot of other enemies here, as well as some marine backup. Slowly make your way around in a clockwise fashion until you get to the far right where you will see a large elevator descending in the distance.
Take Lift to Control Tower
Head to the elevator and be prepared for a Shock Troop waiting for you there (throw a grenade in preparation if you have it). When he is dead, activate the lift to escape the incoming hordes of enemies.
Defend Control Tower
Run down the ramp and use the turret to take out the Seeker ship and associated ground crew. Leave the turret and use the elevator straight ahead once it becomes available. Go through the door at the top, taking out a whole lot more Seekers.
Proceed Across Bridge to Command Center
Go through the next door and run along the bridge until it collapses.
Find Way Into Command Center
Go straight ahead and use the elevator to descend. Help out the marines to the left, then enter the Command Center (don't wait for the enemies to stop spawning here).
Find Admiral Torn
Go straight through to the back of the building and up another elevator.
Go back down in the elevator and outside the Command Center, then hop in the Scythe.
Proceed to Northern Medical Platform
Drive straight ahead up the ramp. Proceed over the narrow bridge to the left and down the other side.
Proceed to Upper Medical Deck
Continue driving straight ahead and turn right twice. Take either path ahead and follow it until you automatically pick up your companion.
Rush to Civilian Launch Deck
Drive through the middle of the area and up a long ramp and bridge. Turn right at the end, then left on to the next bridge - when this starts collapsing, use your turbo at the end to make it across the gap. Turn left, then right, and drive down a tunnel, then turn either way at the end to get outside. Go through the middle and down into the bottom section to a waiting ship.
Chapter 4: The Awakening
Proceed to Dojo to Complete Your Training
Go through the portal straight ahead. Turn left, then enter the first portal on the right, then the first on the right again to find the dojo. Approach the Aurelian behind the pool of water.

Proceed Across Seeker Destroyer Surface
Go forward and up the orange elevator, then turn around and take care of the Seekers, grabbing one of their weapons. Go up the next elevator, then continue forward and up a ramp. Ignore the tunnel and jump down to a lower platform to the left, then jump to a higher platform ahead. Follow this path around, killing more Seekers, then use the console at the end. Cross the bridge and go through the next door.
Find a Way Into Seeker Destroyer
Go through the doorway and clear the room of Seekers, then go around to the left. Use the large gun as a platform to jump across to the next walkway, then turn around to the right and go up the orange elevator. Use a console to extend a short bridge, then go through the newly accessible door. The door at the end of the hall is just hiding 2 Seekers, so kill them before going up the orange elevator on the left. Jump around the following path, use another console and cross the bridge. Go up one more orange elevator, then make your way around the corner to the right.
Defeat Seeker Elite
You will receive the Surge power just before this boss battle - make sure you equip it. Dodge the enemy's attacks and target it with a series of 3 Surge attacks to kill it.
Stave off Initial Seeker Assault
This is the largest battle yet, but your allies will come to assist you. You will need to use a combination of your powers and weapons.
Proceed to Destroyer Bridge
Go through the raised door, then follow a series of doors with green lights above them to make your way through the ship. When the path forks, head right and use the elevator. Kill a larger group of Seekers in the hall at the top.
Find a Way Back to Enorym
Go back down the elevator, then go over the narrow bridge through the middle door. Turn right and proceed through several more doors.
Find and Aid Enorym

Continue through a doorway in the back and around to a corner where there are 2 Seeker Elites waiting - take them out one at a time. Go into the next room which has a series of lasers - use your powers to throw the enemies into these as you snake your way through the room.
Escape from Crashing Destroyer
In this sequence, you just need to run and jump as the ship falls apart around you - several times you will need to jump or dodge forwards to make it over gaps as they appear.
Find Survivors in Sinking Wreckage
Start by finding a weapon and equipping a power. Go forward and drop down, then turn around and follow the passages. Kill the lone Seeker, then use a charge jump to reach the upside-down doorway. Once the door implodes, kill another Seeker, then look down over the edge to kill some more. Now drop down (you will only take a little damage), then climb up some wreckage and go through a door in the back.
Proceed Through Canyon Towards Arnyss
Try out your new Negate power to create a shield while you blast the Seekers. Head through the lake and kill a few more enemies before getting into the Seeker Tank. Take this through the canyon and up to a narrow land bridge, then get out and go on foot. Kill the Seekers in the cave, and follow it around to the left. Climb up, then jump down off the ledge to reach a beach.
Survive Until Help Arrives
Set up a negate shield and defend yourself until the chapter ends.

Use your new Aeon Pulse power to kill a lot of Seekers, and eventually Kchell will run away through a door in the back of the area.
Pursue and Capture Kchell
Follow Kchell through the first doorway, having a Negate shield ready. Take care of a lot of Seekers, some of which have rocket launchers near the end. Eventually you will need to take down a ship outside using your Aeon Pulse, before following Kchell through another doorway to the outside.
Defeat Barrakka Bahma
Approach the enemy with your negate shield and try to push him off the edge with a Surge. When he looks to be charging up, get a charge jump ready and you will jump over a ring of fire; now immediately use Surge to knock him off the edge. He will return on top of his ship. Run back towards the door you came through, stopping on the platform just before it, then ready your Negate and Aeon Pulse powers. After he fires his weapons at your shield, run out and blast one side of his ship. Repeat this until it is destroyed, and he returns to the far platform on foot. Repeat both stages of the battle a second time, but targeting the other side of his ship. On the third cycle, aim directly for him on his ship and you will eventually defeat him.

Go up the path to the left and continue uphill. Battle a lot of Seekers as you run up to the temple entrance, then keep shooting and using grenades until they stop coming through. Now approach the doors.
Proceed to Lower Temple Annex
Follow the corridors until you reach a gap to jump over - make sure you kill all the enemies before jumping across. Continue down the next hall, then go through an opening to the right. Throw a couple of grenades down to the bottom to keep the enemies, then make your way down by going around the edges.

Use Console on Lower Level to Open Door
Drop down and kill the Seekers, then use the flashing console.
Proceed with Aurelians Across Upper Hangar
Use the elevator to get back up to the Aurelians, then go through the door near them with the green light. Kill some Seekers as you walk over the raised platforms, and take out an enemy ship before the door ahead will open. Keep going through another corridor with lots of breakable windows, then use the elevator at the end to go further up. Head around the corner to the right and kill another group of Seekers and another enemy ship.
Use Cargo Lift to Access Lower Hangar
A large platform will rise up through the middle of this area. Kill the few remaining Seekers, then use the console on this platform.
Defend Aurelians While They Open Door
Keep killing the waves of Seekers until they stop coming, then head through the door at the bottom of the area - it won't open until all the Seekers are dead.

Proceed Across Volcano Rim
Follow the Aurelians straight ahead and then to the left, and take out a group of Seekers. Go down the ramp and through the door at the bottom.

Make Your Way Across Volcano Valley
After the left path collapses, turn to the right. Take this trip slowly and methodically, taking out the Shock Troops and Seeker tanks from a safe distance. Remember you can go back to the hangar and take the other Seeker tank if this one becomes too damaged. Once you eventually reach the next building, stay in your tank until the doors open, as there is an enemy one just inside. Once it is destroyed, head inside on foot.
Infiltrate Seeker Detention Center
Go through the doors and kill the Seekers at the consoles. Turn right and go through the doors, then over a bridge that will collapse. Climb up what is left of the bridge and go through 2 more doors.

Defeat Cell Guards
Go through either door and kill the cell guards on the level below.
Chase the huge creature through its tunnel to the outside.
Dodge the attacks, and jump whenever the Skinwalker punches the ground to avoid losing your balance. When he picks a boulder up and has it above his head, charge up your Surge and fire it at him - he will drop the boulder on his head. Quickly attack him with your strongest power while he is stunned. Repeat this sequence until he is defeated.
Run over the broken bridge ahead and kill the Shock Troop and Seekers. Approach the Seeker tank on the left.
Escape from Volcano
Get in the Seeker tank and head down the tunnels, destroying all enemies along the way.

Kill the 6 Seeker snipers in this area. Go up the elevator on the left, and then down the other on the right. Get into the Seeker tank and follow the path ahead. Make sure you go up the grassy slope on the right when you can. Once you reach a lava area, swap into the new Seeker tank, as yours is probably quite damaged. There are lots more enemies through this tunnel, but eventually you can go up a ramp at the other end. Clear the enemies here (they will keep slowly re-spawning), then get out of your tank and go to the right. Keep shooting as you run through the final exit.
Epilogue: Pulling Strings
Defeat the Koroem
Quickly run to the left and stand next to Marin. Set up 2 Negate shields, one to the left, one to the right, and one straight ahead. Stand in this spot whenever the Koroem is sending in blasts from the sides, or attacking with its red attack from the front.
When the Koroem forms black energy ball and throws it at you, run out from cover and use your Surge power to knock it back 3 times. While the Koroem is stunned from this, use Lift to pick up the smaller rocks and throw them at it. Repeat this cycle until it is defeated.
After the short interlude, quickly run at the Koroem and use your Lift power before it can attack.
Just wander around until you are almost dead and you will be saved.
