While the 2008 Presidential battle royale between Obama and McCain reaches a fever pitch today -- video games are waging war in the background. This week, Gears of War 2 and Resistance 2 go head to head and now, the power struggle between Rock Band and Guitar Hero continues, as supermodel Heidi Klum performs a strip tease in a new commercial for Guitar Hero World Tour.

We have to admit, this isn't as big a score as convincing The Beatles to release its songs for your game (or at least to the developer who makes Rock Band), but Guitar Hero publisher Activision still gets an 'A' for effort.

Watch Heidi dance in her skivvies below:

    Spore, the highly anticipated game from the creators of The Sims, gives players their own personal universe in a box. Create and evolve life, establish tribes, build civilizations, sculpt entire worlds and explore a universe created by other gamers. Spore gives players a wealth of creative tools to customize nearly every aspect of their universe: creatures, vehicles, buildings, and even UFOs. Players can then seamlessly share their creations with the world or explore infinite new galaxies created by other gamers. (Screenshot 1 of 112)
