This is the sixth console generation version of Splinter Cell: Double Agent. Unlike its next-generation counterpart, this version was developed by Ubisoft Montreal, the folks behind the original Splinter Cell as well as Splinter Cell: Chaos Theory. This one still has a stealth meter (and not the binary visibility system that later titles featured) and sound meter. It's essentially Chaos Theory 2, and I'd love to be able to play it without having to dig my original Xbox out of mothballs.
