Driller

Drilled wall; notice the material texture

Drillers are tools capable of creating holes on walls of a distinct, bronze-like material. Tools can be placed through the hole, but it isn't big enough for a human to go cross to the other side. Laser beams can also go through holes created by the driller and it may also be used to gain line of sight with a Teleporter, a different body, or another drillable wall.
