The Apocalypse is the gun with the #1 most damage in the game. It is a heavy class gun, but it increases the player's speed instead of the usual decrease. Its RPM is very low and its projectiles explode after a short time, making it semi-ranged special heavy like the Coronal Ejector and Event Horizon. Its projectiles appear to be large fireballs, and emit radioactive symbols as particles. The projectiles explode in a mushroom cloud shape, which causes quite a bit of clutter. It has a huge splash radius and does a lot of splash damage. Nothing can survive a blast from the Apocalypse.
