Beat Hazard is a pretty fun, Asteriods/Warning Forever style title that uses music to generate levels for you to play in.
Beat Hazard - Xbox360 Indie Games (http://www.youtube.com/watch?v=ASusmLRreXw#lq-lq2-hq-vhq-hd)
Released for Xbox 360 LA (i'm assuming) and PC (steam)
The volume, tempo, beats, etc of your music will power your weapons, along side power up items you can collect from defeated foes.(all songs are adjusted to play at a certain volume, so you can't just make loud songs to be constantly hyper powered)
All in all, it's a new type of audiosurf like experience, where I hope people will have most songs with recordings uploaded and played.
It costed me 7.50USD.
Seems like a awesome game, i may go and buy it soon.
I bought Geometry Wars: Retro Evolved 2.
dammit
It's pretty great, i'm hoping to record a buncha gameplay eventually and put 'er up on jewtube.
