ScoreDoom makes playing & re-playing Doom wads more fun in both single-player and multi-player co-op, without changing the standard Doom game-play and feel. ScoreDoom is built from the modern sourceports GZDoom & Skulltag, so it has modern OpenGL graphics and client-server architecture. It adds an arcade style scoring system to Doom. Points are primarily scored when shooting/killing monsters, achieving map objectives, finding secrets & map items in the quickest time possible. Points are also scored in many other fun ways, like chaining kills together in a short time, causing extreme (gibbage) deaths, heck, even blowing up barrels gives points etc. There are high score tables you can set locally, or take on other players across the world on the global online high score leader-boards! Else take on other players around the world directly in competitive online co-op mode! ScoreDoom also has an Add-on Pack that adds up to 300 new Doom-like enemies, many new power-ups and other cool stuff.
When playing with the ScoreDoomST Add-On Pack, finale levels like the Phobos Anomaly (E1M8), and its Ultimate Doom counterparts (E2M8, E3M8, E4M6, E4M8), will have a 'Boss Rush' mode whereby the players will be required to defeat a series of bosses to complete the finale. The footage also show-cases the extra content the Add-On Pack provides and how it strives to remain true to the Doom look and feel, and most importantly gameplay.
E2M8 (Tower of Babel) and E3M8 (Dis) have equivalent Cyberdemon and Spider Mastermind Boss Rushes. Actually any wad which has a level flagged as a Baron of Hell finale, Cyberdemon finale or SpiderMastermind finale will trigger a Boss Rush when playing the with ScoreDoomST Add-On Pack. These include Doom2 based wads like Console Doom.
Note: ScoreDoomST is still in beta, and for the final release, there will be less health dropped to make Boss Rush even more competitive.
