Welcome to "Uncharted" on iPhone. As with so many of Gameloft's games, Shadow Guardian sticks to the script of its inspiration. This is not a homage, but a clone, right down to the smart-mouthed protagonist, facing off against an army of mercenaries in a search for treasure.

What Shadow Guardian lacks in originality, it makes up for in production values. This is one of the best looking games I've seen running on an iPhone 4, and it's undoubtedly one of the most complex as well. None of the fundamentals of Uncharted's gameplay has been sacrificed in the basic design's transition to a portable device: You'll be platforming, gunning and punching your way through some impressively large levels, with a fully-voiced story to boot.

Shadow Guardian's platforming will be immediately recognizable to Uncharted players, offering the same skill-free approach to leaping and climbing around environments. Like Nathan Drake, the game's main character has super-human hand strength, and the virtual analog stick effectively guides his remarkable acrobatics, which "look" a lot more difficult to perform than in practice.
