The Legion Assassin is a Cerberus-controlled geth platform guarding the remains of the Human-Reaper in Cronos Station. It only appears if Commander Shepard sold to Cerberus the geth unit recovered from the Derelict Reaper in 2185.

Unlike its counterpart, it never speaks, only vocalizing with electronic geth chirps. It is encountered in the catwalks surrounding the Human-Reaper remains, descending from a ladder after two Phantoms precede it.



Legion Assassin is armed with a M-13 Raptor sniper rifle. It has no offensive capability at melee range, and will attempt to run away to line up a shot at range if cornered.


Legion Assassin has moderate health and shields.


  • Legion Assassin is essentially a named Nemesis, except synthetic rather than organic. Most tactics for beating the common sniper unit also applies to this platform.
  • Because the location where it appears is essentially a narrow corridor, it has little room to maneuver to line up a shot. Rushing Legion Assassin will render its best attack unusable.
  • It would be wise to Biotic Charge Legion Assassin as a Vanguard. This should stun it, rendering it vulnerable to a heavy melee.
