Tyrannizer is a first-person shooter game with a mix of science fiction and fantasy elements, probably inspired by Quake. The player character uses a sword as a melee weapon along with modern-era firearms, but the game is set in a medieval-looking castle populated by mythical creatures.
The game was developed with the ACKNEX 3D GameStudio construction set, which is more similar to the Build 2. 5D engine than the true 3D Quake engine, and uses sprites for enemies, objects and decorations. Advanced features similar to the Build engine are used, such as bridges or balconies that can be walked over and under, and the ability to swim underwater.
