Not sure what to dress up as this Halloween? Why not go with one of the many game characters to rock the charts this year? There are plenty of choices for guys, girls and everything in between.
Assassin’s Creed II:

For the loner type, hanging out in the corner with a beer, just watching everything that goes on, Ezio may be a great choice. He’s cloaked, cool and a little homicidal; the perfect look for the mysterious sociopath that likes to nab the Goth girls.
Batman Arkham Asylum:

Arkham is full of muscle-bound men and vivacious vixens. Couples cheesy enough to actually show up in team attire can arrive arm in arm as The Joker and Harley Quinn. Solo trick-or-treaters can come as any of the many awesome villains lurking the halls of Arkham: Scarecrow, Poison Ivy, Bane, or Killer Croc. And of course, there’s always the Bat himself for party goers with a hero complex.
The Beatles RockBand:

Ever since the first plastic guitar controller was placed in the hands of the players, this game begged to be made. Beatles alumni and new fans alike can suit up as the fab four and rock the party.
Brutal Legend:

Metal fan can slap on some wrist bracers, leather, and a lot of hairspray to take on the persona of Eddie Riggs: the coolest roadie ever to hit the consoles.
Ghostbusters:

The Ghostbusters came back with a vengeance this year and it was as if they’d never even been gone. Suit up as Peter, Ray, Egon, Winston or even yourself, and make sure Slimer doesn’t ruin the cheese spread.
Halo 3 ODST:

This was the game that was supposed to be a movie. Instead it became an underdog ‘expansion’ that put Halo fans center stage. Tweak that old motorcycle helmet collecting dust in the garage and borrow your little brother’s paintball gun to become one of the coolest soldiers ever conceived. We are ODST.
Mario and Luigi: Bowser’s Inside Story:

There’ll probably be a lot of Marios, Luigis and Peaches out there, but it’s about time Bowser got a little love. Put some extra effort into the sewing machine this year and show up as everyone’s favorite bumbling bad guy.
Overlord II:

If you’ve got a horde full of youngsters, you should come as the Overlord and his minions. People won’t care as much that you brought a brood of children to the party if they’re dressed as demons.
Resident Evil 5:

Big, buff dudes can show off their pecks as Chris Redfield and hot chicks with guns can work a shotgun as Sheva. Those people really strapped for cash can simply shred up some clothing and buy a machete to transform into one of the hordes of zombies.
Uncharted 2:

Uncharted’s Nathan is quite obviously this generation's Indiana Jones. Grab some cargo pants and a wrist cuff watch before packing some heat. Ladies don’t have to be left out of this one either. Nathan’s battling beauties Elena and Chloe will definitely get some stares. Crash through the window with a tumble for an even bigger entrance.
WET:

Girls, Ruby is hot. She is the girl gamers’ answer to dressing up as a slutty nurse… Only way more bad.
Wii Fit Plus:

Those with awesome bodies can take the easy approach and show up as one of the Wii Fit trainers. Keg stands probably count as a yoga move. Or, at least, they should.
