The Vanisher looks identical to the M4A1, but bears red markings all over itself. Its bullets are red and red flames fume out while firing.
The Vanisher requires no specific chapters to be completed or gamepass and can be bought for $40000 at the beginning of the game as long as the player's level is at least 32.
The Vanisher is one of the few guns in the game that isn't based off of any real life firearm.
