i dont know how to mod i tried... no idea what i'm doing haha. but i think it would pretty amazing if someone made a collection of WWII guns, like the BAR or the thompson sub machine gun, both the M1A1 as well as the chicago typewriter. and the ever popular M1 Garand, the Mauser 98k, and Nagant models for the Chinese. there are plenty of weapons from that era i think would be a great mod add for L4D2
