3. Mark Of The Ninja
From one 2D side-scroller to another, and Klei Entertainment's innovative 'stealth goes 2D' mishmash of styles is more solid than Clash of Clans' sales figures. By applying the studio's incredible art design and eye for fluidity in character movement with abilities and level layouts that are a dream to play, you'll rocket through the healthy 15 hour campaign and be begging for more. Your ninja's abilities are upgraded and fleshed out in the coolest way after every couple of environments, unlocking everything from spike traps to gliding kills - even a time-freezing teleportation ability lets you disappear in a cloud of smoke if you get spotted. If the heart of the best stealth games is in letting you feel like an incredibly powerful character, rationing out the pain in short bursts by way of dazzling special abilities and confident, tactile controls, Mark of the Ninja is outstanding.
