The player is placed in the middle of the map while enemies gradually enter and make their way towards the player. The player has to eliminate the enemies before their health reaches zero. With each death of an enemy the player will gain experience points. Each level the player gains, the player can select special perks that range anywhere from faster reload times, faster shooting speed, faster movement, to status effects like radiation (creating an area of affect around the player that damages all enemies within its range), poison bullets, and many others. Randomly, when an enemy is killed they will drop a power-up that may be extra points, temporary invulnerability, fire bullets, slowing of time, and many others. The game also offers local multiplayer for two players on the original and up to four on the re-release. In a multiplayer game, all players share the same experience and perks but are free to pick up any weapons or power-ups that may appear.

Originally developed by 10tons Entertainment and released as freeware/demo version, in 2003 a commercial shareware version with publisher Reflexive Entertainment followed. The game was re-released and self-published through digital distribution in 2014 with updates to graphics, perks, weapons, enemies, and game modes. In 2015 it was released for the Xbox One and later for Nintendo Switch in 2017.
