Quick! Duke Nukem 3D Megaton Edition is on the Humble "Awesome Games Done Quick 2015" Bundle! The pay-what-you-want deal is available for a few more days, allowing you to grab ten games and some loot for next to nothing. Since Duke Nukem's online co-op version is there, might as well indulge, right?
The game's been hacked, modded, beefed up and overhauled many times since its 1996 release, but any co-op gamer will agree that Duke Nukem 3D Megaton Edition with its online multiplayer is the Duke Nukem game to own. Play through the campaign with up to eight players, climbing across scaffoldings, offering money to strippers, and "saving" nearly naked ladies from the clutches of evil alien plant things.
Other games in the bundle include Shadow Warrior Classic Redux, Oddworld: Abe's Oddysee, Volgarr the Viking, Escape Goat 2 and Shantae: Risky's Revenge - Director's Cut. Duke is available for literally next to nothing, but if you want Steam keys, you'll need to pay at least $1. The bundle will be available until the weekend, so don't dawdle. Also, don't use the word "dawdle" unless you're a 1930s grandmother living on a farm in Iowa.
