Most FPSes nowadays are just mindless clicker games with guns. The Cerberus Project rejects all of the dumbing down of the last 15 years, and instead builds on the greatest FPS games with unique features such as analog sword movement, original weapons, and new types of enemies. The Cerberus Project does not have any unnecessary RPG elements, cutscenes, randomized level design, or checkpoints.

Dodge a hail of projectiles and fight hundreds of fast melee enemies at once to reach the powerups you need to survive.
The Cerberus Project is hard to learn, and harder to master. No design concessions were made for casuals.
