While there is undoubtedly a core player-vs-player component to the game, teaming up with four friends to take on an A.I. controlled team is fully supported. However, it's worth noting that those options are somewhat limited at this time. Originally, there were plans to allow up to four players to team up locally, online, via LAN, or some combination thereof (combo co-op). Things happen, understandably, during development and now it looks like the co-op is a bit more limited. You can play any of the available modes (Season, Playoffs, or Arcade [Play Now]) with up to four players locally with couch co-op (i.e., all players on the same PC looking at the same screen) using four game controllers.

The big selling point of Mutant Football League is the brutal way you can take down the other team. Tackle another player just right and they may be going off the field in a series of Ziploc bags. You can even take out the refs, though there are penalties for such things. Along with "Nasty Audibles," which include plays like having your runningback pull out a chainsaw and go after the opposing team, and players getting fitted with brass knuckles, hand grenades, clubs, and other weapons of destruction, you'll have to contend with the playing field itself. From land mines to lava flows, nowhere is safe.
