Do you remember Steel Storm: Burning Retribution? I barely do, and yet I loved it back in May 2011. A top-down shooter that mixes action and puzzles, sneaking up to the edge of bullet-hell. Bizarrely, two and a half years later, a small piece of DLC has appeared – Forgotten Prison. Still, it’s a darned good one, and it’s a reminder that people should pick up the entire (really very cheap) core game.
