The Steam Summer Camp Sale is now underway, offering a bunch of one-day deals on a number of games with discounts as high as 75% off, with new deals to be offered every day between now and July 10th. There's also a Summer Camp Prize Booth offering the chance to win in-game content, along with a grand prize giveaway where 100 winners will get the top 10 games on their Steam wish lists. Here's word on how to earn in-game items as part of this promotion: "Play games to earn special Steam Summer Camp Steam Achievements. Each one earns you a Prize Ticket. Then, redeem your Prize Tickets for all kinds of in-game content (cars, maps, hippos, hats, and more...). Prize tickets must be redeemed during the Steam Summer Camp Sale."
