About: This mod adds a credit system to Doom. You earn credits by killing monsters or picking them up throughout the map. Once you have enough credits, you can buy new items in the Gun Shop, in-between maps. Note: This means you can no longer find weapons lying around levels now.
Protip: This will work for both single player and co-op.
Compatibility: Skullag exclusive, as usual. Doom II only, as well.
