This is a fun physics model my friends David, Steve and I made and have been evolving over the past, well 14 years. We tried to keep it very simple, and they are really just more of weapons tweaks that make the game even MORE fun if you can imagine that! Few highlights: Pistol gets 3 "sniper" fists, that will take you down to 10% health. Machine gun more powerful at close range but less further out. Missile launcher has a second trigger that can launch mini SAM missiles(bunch of them), SMG second trigger makes a slow fire wall. It's the little things that make Multiplayer fun for ever ;)
