I see you were partially inspired by my ehh19 physics.
(playable with every gametype)
my first file which overpowers the players weaponary, here are the changes I made: pistols: shoots rockets, fusion: no change, Shotgun: single weild and shoots grenades. AR:100 bullets and 2 grenades, SMG:no changes, Flamer: no changes, Missile launcher: shoots one rocket(makes rocket launcher feel more modern), alien gun: shoots staff bolts that can launch an enemy upwards if aimed at the right spot, most effective at close range.
