Shovel Knight Showdown finishes off the Treasure Trove for Shovel Knight with an arena brawler. Its not going to topple Smash, but it proves fun for gamers who have been with the title for the past six years. Strangely, it is also available as a standalone, which this reviewer got to try cold turkey with mixed results.
