Hitman: Sniper Challenge is a game that was developed as a pre-order incentive for Hitman Absolution. That said, regardless of whether or not you pre-ordered Absolution, you can now play Hitman: Sniper Challenge for free. The game is available on Square Enix’s Core Online website, and plays right in your browser.
If you’re curious, we did a short playtest of Hitman: Sniper Challenge last year. You can read that here, rubber duckies and all.
Additionally, Gyromancer, a Square Enix puzzle game that plays similarly to Bejeweled and Puzzle Quest, is now available on Core Online as well. Interestingly, development of Gyromancer began after a PopCap employee happened to visit Square Enix’s Japan office.
