This is one of, if not the best, modern ports of Duke Nukem 3D out there. I have it on Steam, but it was de-listed from the Steam store when Gearbox came out with their vastly inferior 20th Anniversary: World Tour version. It contains all 4 original episodes, as well as the 3 main expansions: Duke it out in DC, Caribbean: Life's a Beach, and Nuclear Winter. Updated to support modern systems & resolutions. Plays like a dream compared to the original DOS version, and the World Tour version (which is more so optimized for consoles / controllers and plays like butt on PC mouse & keyboard unless you do some tweaking). Until they make the Megaton edition available again, might as well stick with eDuke32, don't waste your money on the money-grab Gearbox slop that is the World Tour edition. COME GET SOME!
