FREE STEAM KEYS: AI War: Fleet Command & 12 Is Better than 6

Humble Bundle has launched its yearly Spring Sale, which is offering a number of discounts on titles, as well as a free full version copy of Galactic Civilizations 2: Ultimate Edition. In addition, this year’s Spring Sale also includes a reward system. People will receive a stamp for every $5 they spend in the Humble Store or for visiting the store home page daily.

If they collect one stamp, they’ll get a 10% discount coupon on Surviving Mars and a 10% discount coupon on Humble Monthly! Three stamps will get users a free copy of the Oldie but goodie real time strategy game “AI War: Fleet Command” while five stamps will earn a free copy of the dynamic top-down shooter “12 is Better Than 6 ”. People have until May 24th at 10am PDT to collect stamps and claim prizes. After that, a new week of rewards will begin. And your stamps will not carry over, so act fast!

To get a stamp, you need to visit the Humble Store main page every day starting today (you must be logged into your Humble Bundle store account), click “Spring Sale – Collect your Spring Sale Rewards” then you get a stamp. After 5 days you will receive both games for FREE! You can see the progress of Stamps here.
