Nemesis (enemy)

The Nemesis is a type of Cerberus unit encountered in Mass Effect 3.

Capabilities
Offensive

Nemeses are armed with a M-13 Raptor sniper rifle.

Defensive

Nemeses are primarily protected by shields, but also rarely leave cover. They will target enemies at range, peeking out of cover only long enough to aim and fire a shot. Because they lack any form of short range offense, and their targetting laser gives away their position, they frequently run to a new position after a few shots to avoid attack.

Tactics

 * While Nemeses frequently give their positions away when shooting at the player due to the bright targeting laser their helmets emit, the glare from the laser also obscures the Nemeses themselves. Attacking a Nemesis at close range is thus more viable than counter-sniping, especially because the Nemesis cannot shoot its weapon. The Nemesis will attempt to retreat to a position further away from the player to properly utilize its sniper rifle, but sustained attacks should keep it off balance long enough to dispatch.
 * Particularly in the later rounds of multiplayer matches, Nemeses are prone to pair up with a Phantom. Because the Nemesis has no close range attacks, and is best dealt with by melee attacks or a shotgun blast, its serve as a very effective lure for the Phantom. Keep this in mind when watching Nemeses move around the battlefield; if they remain in one corner for an extended period, they are likely being used as bait by a nearby Phantom.
