Tom Clancy's Splinter Cell: Chaos Theory is 75% off on the Ubisoft Store. The PC version now costs $2.50 instead of its regular $9.99. This entry in the long-running Splinter Cell series focuses on stealth: you slip through shadows, plan your approach and deal with threats without raising the alarm.
It's a good fit for fans of patient, tactical stealth games, for anyone who has wanted to try a classic in the genre, and for series fans who want to fill a gap in their collection without spending much.
Once you buy it at the discounted price, the game stays on your account permanently. When the sale ends, only the price goes back up. No end date has been announced, so it's worth grabbing it while the discount lasts.
