Chris Buffa (Modojo): Contract Killer 2 for iOS and Android, similar to its prequel, lets players take on the role of a sniper, charged with snuffing high-value targets. That said, you don't take into account distance or wind. The game doesn't hide its arcade nature. Instead, you simply zoom in, line up virtual bad guys and put bullets in their heads, the result of which produce satisfying splashes of red. To that end, this sequel serves up a similar experience with new weapons and other toys to play with, along with different locations and perhaps the best feature of all, silent takedowns. Blasting bad guys is fun, no question, but there's something to be said for killing them with throwing knives, or sneaking up behind an unsuspecting enemy and bludgeoning the poor sap with brass knuckles.
