Remember good old Duke Nukem 3D? Well i do, and used to play it frequently, it was a very popular FPS like Doom. Well the good news is that Duke Nukem 3D has become abandonware meaning you can download and install the full version for nothing. This in itself is not that exciting, that part is that a few people have worked on a Hi resolution mod for this game and made it look very nice and it is also available for free, 191MB!!! much larger than the game.
