There are several points in the game where, should you progress too far, you will be unable to go back to previous areas to pick up missed items or collectibles.

Some achievements' progress does not save across playthroughs. Be careful to not lock yourself out of getting some by reaching certain parts of the game! You will have to load a previous save or start a new playthrough if you miss anything! Here are all the points of no return I know of:

Beta Grove: Destroy all the cameras and pick up the items/collectibles you want in here before progressing to jettisoning the grove .

Levels R to 7: Destroy all the cameras/CPU nodes and pick up the items/collectibles you want in these sections before progressing to Security (Level 8). Also keep in mind that you will lose access to any recycle stations once you enter the next area.

Level 8: Destroy all the cameras/CPU nodes and pick up the items/collectibles you want in this section before progressing to the Bridge (Level 9). Also keep in mind that you will lose access to your cargo lift once you enter the next area.

Level 9: Destroy all the cameras in this section before entering the area unlocked by the Isolinear Chipset .


They can be found later in the game, located in Level 7 - Engineering .


Proceed at your own risk.

Go to the westernmost section of the area. You'll see a gap in the ceiling; jump up there to reach the skull.

Leave the room with the cargo lift and take the first door to your left. Go straight until you reach a left turn. There will be a dead body there. Look up.

Leave the room with the recycler and take the first door to your left. You will see a ledge next to a door across from you. Get on that ledge and jump up again to reach an alcove with the skull.

Leave the room with the cargo lift and take the second door to your right. Walk forward, step through the next door, then turn right. At the end of the hallway will be an opening above with the skull.

From the recycler, look southeast. You'll see a small door above. Jump from the crates below and crouch in midair to crawl inside.

Head to bay 1 in the northernmost section. Jump on the ship, then jump again to the balcony above.

From the power station looking east down the hall, take the second door to your left. There will be a gap in the ceiling in this room.

From the central section connecting all four quadrants, jump on the southern metal supports until you reach the skull.

From the northern force bridge leading to... the Bridge elevator, look south toward the central tower. There will be an alcove slightly down to your left on this central tower; glide there and open the door for the skull.

From the mod-kit station, look north. There will be an opening in the ceiling. Jump up the ledge for (what should be) your last skull.

Hopefully this helped you.
