Backbreaker's addictive Tackle Alley minigame put you on the field as a ballcarrier juking and spinning his way through 100-yard touchdown runs. Backbreaker 2: Vengeance puts you in the game on defence, blasting those showboats out of the water.
Backbreaker 2: Vengeance, the iPhone (and iPod touch)-only sequel to Backbreaker: Tackle Alley, hit the iTunes store last week. In it you get more moves on offence and a "super showboat" move to rack up even higher scores. On defence, all of those moves are available to you save showboat; instead you're going to hunt down the opposing runner and clean his transmission. As you progress through the game you unlock teams for use and additional moves, although the full set becomes available to you early in the game.
One note here, there's no game audio, just my narration, because of a technical difficulty on my end (basically, I'm in the stone age filming with a tape-based mini-camcorder, and it has a squeaky gear that makes everything sound like your roommate having sex. You should see my newborn cousin's christening video, it's awesome.) I'm trying to get that fixed. But if you've played Backbreaker on the PS3 or the Xbox 360, the sounds (including in the menu) are consistent with that game's look and feel and the roar of the crowd is top notch.
