Reaver
From DoomWiki.org
Reavers are an enemy in the game Strife. They are human-sized and anatomically-humanoid robots that have 150 hit points and carry both a small blaster which is like a double strength pistol, and can slash at close range. They can also do damage to the player or nearby characters with the explosions that result from their destruction. They do not obey alarms, attacking even if one is not activated, so it is important to always be on guard for them. Destroying a Reaver alerts nearby enemies to the player's presence.
