Duke ascends a skyscraper to stop the aliens from they're bullshit. 17 amazing levels 15 different designsers. You have to pistol start all of them witch at first threw me off but slowly came around to actually enjoying. I beat it without save scumming at all and let me tell you its called DUKE HARD for a reason. Sexy set of levels specially the rooftop finale. Eduke32 sorce port for some odd reason wont let you fit under the railings to get the yellow key card in the last level rooftop so you may have to clip to get thru. That was ass but not the mods fault.
