M68 Gauss cannon

The M68 Gauss Cannon is a weapon that fires hypervelocity, high-density projectiles similar to those of a MAC gun. It is mounted on the rear of the M12G1 Warthog LAAV. It is very powerful and very useful against vehicles. However, it is not as effective against infantry as the M41 LAAG, which is also mounted on the Warthog. This is because there is little splash damage and it has as slower rate of fire, but a direct hit will kill most enemies in one shot, two if they have an Overshield. Due to its power and speed it is a good weapon against Wraiths.

This weapon uses a set of magnets to propel a 25mm slug of depleted uranium, a very dense, heavy metal, at high speeds. The raw mass and great speeds of the projectile is the key to the stopping power and performance of the Gauss cannon. Unlike the chain-fed system that the M41 machine gun uses, this cannon uses a tube to draw slugs from it's ammunition drum mounted below the cannon.

In Halo 2, this version of the Warthog seems to have replaced the M12A1 LAAV version of the Warthog, which featured three Rocket Launchers. That version became problematic due to the prodigious reload time necessary for the launchers.

This Vehicle made its debut in Halo 2. However, with the footage shown to the EGM people during their stay at Bungie, where Master Chief boards a Gauss Warthog.

Trivia

 * It is possible to knock a Covenant Sniper Tower off its anti-grav pod by shooting it with the Cannon.
 * Using the Gauss Cannon you can make a Combat Barrier bounce around by shooting the base of them.


 * During the Halo 2 demo trailer, the guass was shooting at a fairly decent speed. Later, in an early beta multiplayer phase the gauss seemed to be slowed down and also seemed to have lost all of its hype. It was later ravamped to its original ROF (Rate Of Fire) during the games final stages.
