It's big, it's bad, it's ugly - for the one looking into the barrel.

The Mechbuster is a huge - and I mean HUGE - recoilless rifle that also uses some principles of a rocket launcher. Three powerful shells covering the main projectile like a sabot propel the high-explosive warhead at the same range as a light gauss rifle, but the shell deals the same damage as a standard gauss cannon - while being one third lighter. On the downside, the projectile is not as accurate as a gauss rifle (it suffers from the fact that the three propellant chambers NEVER ignite and burn out at the same time before they fall off, slightly making the warhead drift), the ammo is as volatile as an inferno round because of all the propellant needed, the weapon generates as much heat as a PPC, and if the ammo cooks off, it does 50 percent more damage to it's own unit than an AC/20 shell.
The projectile has two fuzes: an impact fuze and a proximity fuze. While it does normal damage upon impact, the proximity fuze may be used to conquer the drift of the projectile and make it go up even if it misses the target (provided it passes near by). However the yield is reduced by one third in this case.
