Metro 2033, Risen, and Sacred Citadel Added to Humble Deep Silver Bundle

The Humble Deep Silver Bundle launched last week and gave players crazy savings on great games, and three games have been added to it. Now, Metro 2033, Risen, and Sacred Citadel have been added to the collection if you pay more than the average of about $5. Everything included unlocks on Steam, where Metro and Sacred Citadel still cost $15 each. SC is a really fun brawler, and is fairly new having just been released in April of this year.
