How it works & what to expect
The original DOS release runs in a WebAssembly DOSBox build on this page. Levels are rescue missions: find every hostage, then reach the exit. The jetpack has limited fuel that refills from pickups, so hovering is a resource, not a default.
Playing tips
Jetpack fuel is limited and refills from pickups, so hovering is a resource rather than a default. Levels are rescue missions: find every hostage first, then reach the exit.
Why it's free
Apogee released Alien Carnage as freeware in May 2007, jointly with original author John Passfield. This is the complete game.
