According to the April issue of Official Xbox Magazine, the upcoming Duke Nukem Forever will have four multiplayer modes: Dukematch, Team Dukematch, Hail to the King, and Capture the Babe.
Each mode's inspiration is obvious, except that in Capture the Babe, the would-be flag has been replaced bya writing female as the treasure. And if the babe starts to "freak out", Duke needs to give her a slap. Where? I don't know. But it's probably going to be the bitch kind.
Maps include a freeway, a casino, an Old West town, and the Duke Burger, as well as the multiplayer-only jetpack. Any experience earned will unlock "phsyical customization rewards". Duke Nukem Forever finally runs out of bubblegum on May 3.
