As it does with so many of its titles, Shadow Guardian HD is Gameloft’s attempt to clone Uncharted, a hit PlayStation 3 fanchise, for iDevices. And while on some technical levels, this app succeeds — the graphics are gorgeous for the iPad platform and it has the requisite blend of jumping, action, and puzzles — it ultimately falls short. What holds the Uncharted series together is a nuanced story with characters you care about. That’s not present here and the game’s flaws are enhanced because of it. The pacing is fine and the combat’s not bad, but without anything tying them together, Shadow Guardian HD ultimately is a mere shadow of a much better title.
