Based on the Warhammer from Battletech (specifically the one in this video: http://www.youtube.com/watch?v=sl4eI3htAuA ).
About this creation
The Warhammer is one of the most famous `Mechs of the Inner Sphere. The design entered production in 2515 and its production continued until the fall of the Starleague. The main firepower for its impressive array of weapons comes from the Warhammer's twin PPCs, which are supplemented by an SRM 6 launcher and a pair each of machine guns, small lasers, and medium lasers. As a result, if this `Mech has one problem, it is with heat-buildup.
The Warhammer is one of the most common 'mechs in the Inner Sphere and is also one of the most feared in its weight class-its sole purpose in its design was to "be able to destroy everything its size and smaller".
Above is one of the Warhammer's Particle Projection Cannons-these weapons are amongst the most powerful weapons available in the 3015 Inner Sphere. They produce huge amounts of heat, however.
Above are the Warhammer's torso-mounted weapons, which give it a notable short-range punch.
Above is the Warhammer's SRM pack and Electronic Warfare Suite, the latter of which allows it to keep itself informed in areas where its sensors don't work particularly well (such as highly urban environments).
Above are the Warhammer's legs, which are well-armored.
