Class 1 Driller

Test unit used to tunnel through semi-molten rock. Fast and very aggressive. ---In-game description

The Class 1 Driller is a lightly armored foe. However its lack of armor is compensated for its fast speed and quick firing reaction which can decimate a ship's armor in seconds. Often it will hide and then ambush a pilot in narrow tunnels. It's difficult to catch a dormant bot without alerting it. Ideally this opponent should be countered with a Homing Missile. The in-game description only shows in the registered version of Descent. In Level 10 onward (plus the first secret level), there exist cloaked counterparts, which upon destruction surprisingly give less points than the normal counterpart.

Trivia

 * In the shareware version, the Class 1 Driller only drops Vulcan Ammo. In the registered version, it will drop a Vulcan Cannon if you don't already have one.
