UFC Undisputed 2010, the highly anticipated follow-up to last year's mixed martial arts video game hit from THQ, came out this past Tuesday, May 25.

LOL hopes you're practicing your rear-naked chokes, striking skills and takedown defense because you have only until Saturday, June 5, to train for GameStop's Ultimate Fighter tournament.

Here's the gist of it:

- You must sign in at participating GameStop locations, of which there are four on Long Island listed below, before the 2 p.m. start of the tournament. (Call stores to confirm start time.)

- Tournaments are capped at 32 or 64 players, depending on the store.

- The winner at each store gets an Ultimate Fighter pack, which includes a $25 Ecko Function online gift certificate, an Ecko MMA Shirt, UFC Training Gloves and UFC Undisputed 2010 duffel bag.

- All tournament winners are eligible to win a UFC replica championship belt and an XBox 360 Elite.
