The octogun is a one of the 9 weapons the player can posess and of the 6-7 they can aquire in the game via purchase or menial acquisition/purchase. It has a limited ammo reserve. It is more powerful than the double-waver (in most cases) but less powerful than the decagun. It fires an oscillating energy beam, and its ammo is quickly depleted. It has a fast repeat rate, and a moderate backfire proximity, and its focus is wide in the crosshairs, but concentrated with focused fire. This makes for a good weapon in close quarters and moderate range fire and where concentrated damage is nesesarry. This is a good weapon for clearing dark hallways and focused fire on slow moving targets. Though it may cause less damage at times, this can be a good street-sweeper for melee fire, and handy in high impact applications.
