Changes

The fourth installment of the series is currently in production and is expected to be released on Christmas, 2008. UDMX is the first WAD in the series to fully replace Doom 2's original 32 levels, boasting several of which are replaced by remakes or "flashbacks" of maps found in previous UDM WADs. 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 passed since the original founding of Unidoom.
