There are games where you blast, and there are game where you sneak. The iPhone has a wide selection of the former, but real stealth games, not so much. Splinter Cell, then, is more than welcome to the App Store.
It's always interesting to see a well-known game franchise fold itself up, suck its belly in a cram itself into the iPhone, but it's not always gratifying: often, the game concepts are fundamentally changed. Remember Metal Gear Solid for the iPhone? It ran on rails, defying a looooong history of free sneaking. (Linear, yes, but still: free.) Metal Gear Solid! On rails!
Splinter Cell swings the other way, reconfigured for the iPhone, but still holding onto third-person shooting conventions. Granted, this is a very Gameloft-y game - I'm pretty sure this is the same engine as, say, NOVA - and the action is much more straightforward than a Tom Clancy game on a console or PC, but the spirit's still there. $13.
