due to the increasing levels of armor on modern tanks and IFV the top engineers at Precision Plains Elder Moose division made the simplest anti-tank rifle chambered in the cheapest and oldest cartridge available to them, 30x173mm. The Cataclysm is an over the shoulder, bolt action, single shot, spring mitigated recoil. using the 30x173mm cartridge made famous by the A-10 Warthog it can sometimes penetrate the armor of a M60. However it should be great fun and is effective in cost when used again
