The game

Beat the clock, clear the castle

Medieval halls, crypts and dungeons packed with ridiculous creatures — bats, giant spiders and mummies all want a piece of you.

Every level runs on a timer. Hit the objectives — monsters down, keys found — before it hits zero, or start over.

A dozen distinct real-world-inspired settings, each with its own layout, traps and creatures to learn by heart.

Several weapons with their own feel and ammo economy — ammo, health and time are all counters you juggle at once.

Soundtrack, cutscenes and outrageous sound effects, in the purest late-90s shooter tradition.

Built on a home-made C++/OpenGL engine: BSP tree, lightmaps, lights, cameras, OBJ/ASE loading — all open source on GitHub.
