I think that, instead of a weapon, if a player is close to an infected player for ~3 or so seconds then they should "catch" it. Basically, its tag. Infected people glow green. You wanna hide and run. No weapons, no magneto stick, just try and survive as long as you can!
Also, sort of like Zombie Survival, if an Infected presses a certain key they should be able to go through props/doors and etc, but move at 1/2 speed. Maybe players could do this too, but at 1/4 speed (So they don't get stuck).
