While legions are summoned, Sieg Wahrheit (the player character) is unable to run and has weaker melee attacks.
The main feature that lends originality to the game is the addition of the 'Chaos Legion', which are supernatural creatures that fight alongside the player. Numerous enemies attack the player in waves, and progress to the next part of the stage often requires defeat of all enemies in the area. The gameplay is primarily action-oriented.
