Are you anxious to jump into StarCraft II? Pre-order it at GameStop and you can get your chance. While supplies last, you can get a beta key for pre-ordering your Standard or Collector's Edition copy of StarCraft II: Wings of Liberty. There is one catch. Once you receive the beta key, you will not be able to cancel your pre-order. So don't expect to land the beta key and cancel out if you don't like it.
