In single-player, each wad/wad-episode and level has its own high score which can be set. A single-player is allowed to log in to a score server which keeps track of the high scores for the IWADs and many famous mods. In co-op, each player competes to score the most points on a map, or across a whole wad, where the competing scores are clearly seen. A points-spread stat is also visible to tell players how far behind the leader they are. ScoreDoom supports up to 4 player co-op. High-score servers are not available for multiplayer.
