Driller [Commodore Plus/4 game]
No sound to be found here... because in space, no one can hear you drill, amirite?
Driller is the first game of the bunch that is made with Freescape, a full blown 3D proto-FPS engine for 8- and 16-bit microcomputers.
So what's happening here? In theory, you are supposed to find the places where gas accumulates and drill into them before the planet explodes from the pressure. In practice, an entire building teleports there when you "place the driller". I have no idea.
Oh, you also have to manage your energy, destroy hostile sentry lazer guns, and solve puzzles that make new areas accessible.
Original C64 version by Incentive in 1987.
Plus/4 conversion by Pigmy in 1990.
