New giveaways: Humble Bundle for Android 3
(2 copies). Hacker Evolution: Duality
(2 copies). Hacker Evolution: Untold
All are open until noon EST 2/25/2013.
This is where I start to get into the "not sure all of the keys work but I'm sure that at least one of them does" area (affecting all giveaways but the Humble Bundle) so I apologize in advance if you win and I send you an invalid key, it's just so much easier to do these through SteamGifts. For what it's worth, if they were used, I don't recall anyone ever telling me they were.
Also, it said I could have 5 additional giveaways but I only was able to make 4. Meh.
