Duke it Out in Doom v3.0 addon

This is version 3.0: you should check out the official moddb page for the latest version

A weapons/game-play mod by CeeJay for the source port EDGE-Classic (Github.com) that allows you to play as Duke Nukem in DOOM. It comes complete with a large and colorful arsenal with which you are encouraged to swap between regularly as many have different strengths and weaknesses depending on given situation and enemy. There is a little more focus on strategy, but still keeping an overall action-packed and fast-paced feel with a lot of devastating fire power at your fingertips. It was designed with DOOM II levels in mind but works fine with DOOM and The Ultimate DOOM.

Note: "ACTION 1" key activates Beer and "ACTION 2" key toggles Night-Vision (when these are available, see icons on the far right of the HUD) and Extra Blood option is recommended to be turned off.
