A galaxy hangs over the battlements. Breach the fortress. Survive the shifting cells. Cross the drawbridge. Fight your way to the Infernal Sanctum - and the horde that guards it.
A single large map for GZDoom with 1000+ enemies on UV (500 on HNTR, full skill level support). Original electronic score with adaptive music that builds as you progress.
The title screen presents the fortress as a scale model:

There are three different variants available:
- fotis.pk3 -- this is the best, contains audio as 24-bit FLAC (RECOMMENDED)
- fotis-ogg.pk3 -- this version contains audio compressed with Ogg Vorbis (if somehow a few megabytes matters to you in this current year)
- fotis-nomusic.pk3 -- this version contains no audio files at all (if you must have the smallest possible download)
