Being one of the most famous total conversions in Duke Nukem 3D history, Last Reaction TC offers you 2 brand new episodes (as said in the text files: E5 and E6) with new art, sounds, cons and modified monsters. Unlike many TCs of the time this one actually captured the original feeling of Duke, especially in the 2nd episode...
While offering plenty of levels with unique and interesting level design (With plenty of challenge), they are very hard to navigate and one may find themselves running around a level for almost half and hour before finding the right keycard to exit the maze.
Only bother if you have PLENTY of patience.
