this "mod" will replace weapon's data and sounds for alien swarm making it feel like Aliens. Furthermore, maps will be made for this mod and the final version of it is going to be released only when i have done it all but i will release a update every now and then for you to try :). enjoy the little demo. I am also looking at the possobility of modding the weapon models, playermodels, aliens so they are truely Alien.
a shot of what i have currently.
