When games have an option for stealth, I will often go that route in lieu of the "blow everything up" method. When games focus on stealth, as with Mark of the Ninja, Gunpoint, or the upcoming Paradise Lost: First Contact, then I take notice. There is something about sneaking past enemies unawares that is more satisfying in some ways than murdering them.
MemLeak looks to be another interesting stealth game, with the twists that it is not as much stealth action as it is stealth strategy, and that players control a squad rather than a single character. Set in a futuristic world, gameplay looks to switch between cyber-infiltration and real life infiltration, though either appear to function on the same basic mechanics. Get in, get the stuff, and get out undetected. That, or get shot on sight.
