Three D Screamers

3D Screamers is a 1995 shareware action game by Virtually Unlimited in which a spaceship races through a fully 3D world of tunnels and open space. It blends DOOM-like corridor shooting with flight-simulator movement and full six degrees of freedom, running at high frame rates on FPU-equipped 68k Macs and accelerated for PowerPC.

Gameplay

The player pilots a ship through tunnels and chambers, mixing first-person shooter pacing with free six-axis flight. Texture-mapped surfaces, shading, and explosions give it the look of mid-1990s Doom-era 3D engines.

Technology

The engine targets very high frame rates for the period and uses texture mapping and shading. It requires a math coprocessor on 68k machines and ships with a separate accelerated build for PowerPC.

System requirements

Runs on System 7.0 through Mac OS 9, on 68k (FPU required) and PPC, with at least 5.1 MB of free RAM and a 256-color display.

Notes for emulation

Because the engine is uncapped, on modern emulators or fast hardware the action runs far too quickly; throttling the host CPU is recommended.
