CRUCIS FATAL+FAKE is a fighting game set in a 3D environment, and it's based on TYPE-MOON's Fate Series. The game requires players to form teams consisting of two characters, a Servant and a Master. The game will end if the Master (or Servant in the case of Illyasviel) loses all their health.
The game offers complexity in both ground and air gameplay, with the ability to side-step attacks and use vertical and horizontal hits (similar to the Soul Calibur series) on the ground, and airdashing and launchers in the air. Matchups in stages are emphasized as different stages feature varying walls, slanted floors, objects, and sometimes even ceilings. Combos can range from 6-10 hits without meter, and most Servants possess a launcher for air combos.
