Head Gun

The Head Gun is a Weapon that appears identical to a Grenade Launcher, but allows the player to pick up and fire the head Gib. This Weapon is selected by pressing impulse 6 or pressing the Grenade Launcher key twice. This Weapon was made by Hellblazr.

This Weapon cannot be found in the world and instead can only be acquired by using the "give all" Weapon cheat. As this Weapon can only be acquired with the impulse 9 cheat, it does not work in Multiplayer.

Note the PROGS.DAT file to install this Weapon does not work properly, the player will need to compile their own version.

Strategy
While this Weapon appears to be a Grenade Launcher, it is very similar in behavior to the Nailgun. This means that the gun itself is relatively accurate, but that the projectile itself can be dodged. Furthermore, due to the firing rate being about as fast as a Shotgun, this means that it is much easier to dodge than the aforementioned Weapon.

Gibbed Heads will be pretty readily available, especially from certain foes like Zombies. The biggest issue is that most other heads will clip outside of the world on death, thereby cutting down the amount of Ammo. Furthermore, the Ammo resets to zero at the start of every level.

Advantages

 * Because it requires cheats, Ammo is never a problem
 * Ammo is also relatively common, since Gibs can appear relatively frequently, especially with Zombies.

Disadvantages

 * Can't be used in Multiplayer.
 * Due to the nature of how it must be acquired, it isn't really useful for general gameplay.
 * Most heads appear buggy, resulting in them falling through the world. This causes issues in Deathmatch, where a player can be prevented from respawning if they are Gibbed.
 * Being as weak as a Shotgun, the only real use of this Weapon is the endless supply of Ammo.
 * Can only be acquired with cheats. As the Weapon's sole benefit is Ammo, this makes the Weapon itself nearly pointless.
