ATTENTION ALL HALF-LIFE PLAYERS. Gordon Freeman is in grave danger and NEEDS your help. He's currently pinned down by the Combine in the City 17, and to defeat them, all he needs is an RPG and a couple of health stations. To help, all he needs is your credit card number, the three digits on the back, and the expiration month and year. But you gotta be quick, so Gordon can secure the bag and release the epic Episode Three!
