Changes

The fourth installment of the series was released on December 31st, 2008. Unlike other entries UDMX is the first entry in the series, UDMX was the first to fully replace [[Doom II]]'s original 32 levels, several of which were replaced by remakes or (called "flashbacks" in the WAD) of maps found in previous UDM WADsUDMX's predecessors. The WAD boasts a new palette that saturates reds and greens and deepens blues. UDMX celebrates [[Unidoom]]'s 10th anniversary, bearing the "X" in its name to represent the ten years that have had passed since the original founding of Unidoomat the time of the WAD's release. UDMX has received much critical acclaim throughout the community, and it has been said to be the best installment of the UDM series and one of the best deathmatch megawads to have ever been made.
