Doom II X-Treme

Doom II X-Treme, D2 Extreme, or simply D2X, is a 32-level total conversion for Doom II released on August 12, 1996 by Chuck Lai. While weapon and monster tweaks were done by him, employing an extensive DeHackEd patch and updated graphics, the 32 levels were created by others with some being edits of official id Software and TeamTNT levels. X-Treme gives a larger HP pool for both monsters and the player, while boosting weapons to a whole new level. For example, the automatic shotgun's fire rate is much faster than the default chaingun.

X-Treme was followed by Doom 2 Extreme Gold in 1997.
