Nintendo has confirmed that New Super Mario Bros. 2 for the Nintendo 3DS will feature a fully co-op campaign. The announcement came during Nintendo's 15th E3 2012 press conference, which was centered specifically on its upcoming 3DS lineup.
The full single-player game can be played with a buddy, but you have to stick together. If one player gets too far ahead, the lagging player will appear in a bubble floating around the faster player until that bubble is popped. If you are an especially cruel co-op partner, you'll most likely get a kick out of making your friend watch as you go on your coin collecting spree.
Speaking of coins, New Super Mario Bros. 2 is all about the gold, as you may have guessed from the gameplay trailer. Coins spew from blocks, sand, enemies, and even random portions of the environment. There are also red rings that turn enemies into gold if you jump through them. You can also snag a golden fireflower, which lets you turn anything you hit into coins.
Nintendo also offered the first details on Rush Mode. It works like this: after you beat a level, your coin total goes into banks. These banks then correspond to difficulty levels. You can then pick one of these packs and the game will choose three levels for you to complete.
At that point, the goal is, you guessed it, to collect as many coins as you can as fast as you can. You'll definitely want to keep an eye out for those golden mushrooms too, since they're worth 50 coins. The big catch for this mode is that you only have one life, so you'd better sharpen those speed run skills right quick.
Should you survive, your coin total will go into your Street Pass bank, which you can then pass to other players via Street Pass. When someone else gets your update, it will pull up your Rush Mode pack for them to play and attempt to beat your score.
Expect more New Super Mario Bros. 2 details as E3 2012 continues.
