Just got Gotham city imposters for ps3 for it im sure it's on 360 also. Its surprisingly really good. Like really good
Half Life 2 is a pretty solid choice if you're looking for a shooter. I finally beat it today and went through Episode One as well. Downloading Ep 2 and I'm bursting with anticipation. Or you could buy the Halo Anniversary edition. Played that today and had a blast as well as nostalgia bombs left and right.
Yeah I played Half Life 2 when it came out on Xbox. It was fun. I'm not sure from that though I can understand the vast amounts of HL hype. Then again I haven't played any mods or the first one, so... I've been playing Bulletstorm recently. Not too bad
Team Fortress 2. I play on pc as i sold my xbox a couple years back, but it is imo one of the best and most balanced shooters on the market right now, and i dont know about xbox, but on pc its free
DayZ is great if you already have a party to join when you start. And be warned the game is very much still in alpha. When things go your way it is good though
Not to sound rude, but he said flash or 360 games. Pretttyyyyyyyy sure DayZ is a PC game. But it's a damn good suggestion, just doesn't fit the categories he wanted is all.
