Energy weapons are the simplest weapon type, but they understandably consume the most energy.
They have the nice characteristic of being practically instantaneous. One energy weapon is the singularity machine gun, which riddles your opponent with a barrage of tiny black holes. Another is the laser blaster, which sends out a ray of minor pain. Mines are released from behind and hover over the surface of the tunnel, waiting for an unsuspecting ship to come careening into them. You can configure your mines by payload and trigger.
