Milk Carton is a Source-engine based multiplayer mod featuring extensive weapon customization. So extensive that is does not even customize existing weapons but allows the player to create their own guns.
v1.2 will feature a hit indicator above the HUD health. It displays what your last shot hit, the damage it did and how far the distance is.
Damage effects parts of the body?
does damage in a certain part of your body cange certain attributes? say shot in the leg and you walk slower shot in the arm and your accuracy drops and shot in the chest and you have to stop walking every now and then to struggle breathing?
reminds me of Deus Ex
