This gametype would use normal DM maps and playermodels. The only change is that the playermodels would be 1/4-1/2 normal size, jump about twice as high as normal (but quickly), and wield knives. Ideally, this would be extremely bloody and violent, but also hilariously entertaining.
0.10.x - Implement size, jumping, and melee weapon as separate mutators.
0.20.x - Combine into gametype.
0.30.x - New models?
