Well, basically just Post-Apocalyptic Skins/ Sprites/ GUI/ Sounds pack for CS:S will include replacement for all weapons. Mod is in active devopment, but we are looking for more modellers, animators or textures.
Well, M4 primaly as M4 skin. It will be without any options probably in full release. It will serve as addon with more user-choice options. This has 3 anims, each with sleeved/ Unsleeved option.Kiyoshi´s aimable animation has even silenced/ unsilenced option.
