Dreamslayer

Dreamslayer is a first-person swarm arena game with retro styling. You play as Argeniton, a holy warrior who has ascended to dragon form, as a demon invasion from beyond the stars engulfs your world.

The nightmare

Argeniton crosses a dimensional threshold to confront Demon Lord Xondadus in his floating citadel of Cazardia, but becomes trapped in an endless nightmare. Stripped of your dragon form, you must defeat the hordes, confront Xondadus, regain your power and break the dream to take your place among the gods.
