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 in certain rooms or through other ways such as from a Mystery button or a Mobile Phone. 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.

Combat Tips
Since there is a guaranteed Heal Button in World 1's shop, you can soak damage for any Anti Droids that spawn in World 1 by charging into enemy droids and killing them quickly so that the Anti Droids that spawned can survive with as much health as possible to help you in World 2.

Anti Droids can chase after Ghost Droids even when they are invisible.
