Although I really like the "28 Days Later" track that is currently used for the game (that's "In the house, in a heartbeat" in case you were wondering), it's important to avoid copyright infringement if at all possible, especially if you want to show your work to future employers or be covered by the gaming press. More than that though, it feels more "professional" to have your own music. Unfortunately I'm not much of a composer myself (read: at all of a composer), but fortunately I know someone who is - a certain Swede called Henrik.
Head over here to listen to the new track, and let me know what you think. An update to Zombie Run is in the works, and will include not only the new music by various fixes, additions and updates! Watch this space...
Okay, I'll give you a hint: my blog is updated every Wednesday :-P
