Humble Bundle is offering a collection of eight games on Steam for $12. As with all Humble Bundles, spending just $1 gets you the first tier of games. It costs more to get games in the higher tiers, but it's always significantly less than if you bought the games separately. This time around, all games come from the Polish developer and publisher CI Games. The Humble Bundle deal goes away July 31.

Spend just $1, and you'll receive Sniper: Ghost Warrior Gold Edition, Chronicles of Mystery: The Scorpio Ritual, and Combat Wings: Battle of Britain. That's not a bad selection of games, especially considering the price. If you pay more than the average amount customers have paid for the bundle, you'll also get the second tier of games, which includes Lords of the Fallen: Game of the Year Edition, Sniper: Ghost Warrior 2: Collector's Edition, and Sniper Ghost Warrior 2: World Hunter Pack. Paying $15 or more gets you the complete bundle, which adds Sniper: Ghost Warrior 3 as well as its multiplayer map pack.
