TouchArcade: Space Marshals [$4.99] is not the dual-stick shooter you probably were expecting – at least not as a mobile game. This is a slow-burning, tactical shooter, eschewing the typical fast-paced, high-score-obsessed affairs that many dual-stick shooters try to be. Instead, this is about stealth, and using sounds to distract enemies, and trying to avoid wild firefights as much as possible. And it's from a company known for racing games. Yet, Space Marshals does a lot right, including with its reward-based loot system. This is the first episode of a series, and there's plenty to look forward to from this game, though there's a solid amount of game here already.
