Max Beland, creative director of Splinter Cell: Conviction, said in an interview with 360 Magazine, “The entire single-player campaign mode will last about seven to eight hours on the normal difficulty setting but be prepared to crank up a couple hours more on realistic.” But he later added that players will be getting at least 30-35 hours of quality gameplay if you factor in Deniable Ops, the competitive multiplayer mode and the coop mode.
