You don't have to win anything to play with the Bungie folks. You just need $15 and another person to play with you. The best part: all the money donated will go towards breast and cervical cancer research.

This is all part of the 4th annual Fight Like a Girl Halo Tournament, and the Bungie dudes are all about saving girly parts.

Want the deets? Look no further.

• Teams of 2 Bungie employees will be playing Halo 3: ODST with YOU
