Steam, the market's leading innovator for promotions to make you buy irresponsible amounts of their product, has struck gold once again with its current Treasure Hunt promotion. Here's how it works: Every two days, four "objectives" become available, requiring hunters to perform both out-of-game and in-game tasks for prizes. For example, current goals include setting up a Steam profile picture, or earning a ridiculously high score in Chime -- which, like all the other games with objectives on the list, is discounted during the two-day period.

Anyone who accomplishes one of the four tasks will be eligible for a drawing at the end of each two-day chunk, through which 20 users will receive five games off their wishlists for free. Anyone who accomplishes 10 of the goals during the entire promotion will be entered to win the grand prize: 100 games of their choosing from the Steam platform. There are also exclusive Team Fortress 2 hats to be distributed to fervent hunters, which, let's be honest, is going to sell more games than all the other prizes up for grabs. People just love them some virtual hats.
