Getting into composing music for games

This is something I have only thought seriously about fairly recently. After watching Hamst3r's Giantbomb Community Song I was inspired to get back into composing which I haven't done since uni. I have mainly rewritten music for section of films such as the matrix and Kung Fu Panda which I might add to this blog at some point. The first step is to build a portfolio of music this time for games so I can use it to show indie developers what kind of things I can do. Also I need alot of practice so having this goal will keep me going I think. My mate knows some Indie developers which live around where I live so after I have got some music together I will use that link as my next step. 
 
My first project is the Mirrors Edge Trailer. I loved playing the game and listening to the ambient soundtrack so I intend to try and recreate that kind of sound and feel the composer gives to the game. I currently have written the underlining rhythm, airy drone sounds for the section before the fight and today i'm going to add some repeating patterns to give it more of a pulse.
