Not hard to do. Do this at the first corrupted station. You can punch the regular enemies and throw stuff at the little fast guys. Reload your last checkpoint if you take too much damage. Make sure you check every room so you don't miss a passenger.
I made an achievement review/tips video to go over this and a few more things.
Also in the comments Freamwhole pointed out there's a corrupted station further in the game with no enemies
