Anti Droid

The Anti Droid is an ally droid that only attacks other Droids.

Appearance
The Anti Droid has a very dark red body color with a bright red helmet and glowing red eyes.

Behavior
The Anti Droid may spawn naturally in certain rooms or through other ways such as from a Mystery button, a Mobile Phone or a Wrath's Edge. The Engineer has the ability to spawn Anti Droids as well.

It deals approximately 2-5 damage to any droids it attacks and has 100 health. The Anti Droid will chase the nearest hostile droid to it, hurting both droids unless one (or both) has a forcefield. The Anti Droid attacks other droids similar to how droids attack players: by simply running into the enemy.

When no hostile droids are present, Anti Droids will stand still.
