If you already own the Power Rangers Deck-Building Game core set, this S.P.D. expansion adds a whole new layer of fun. It introduces the Space Patrol Delta (S.P.D.) Rangers and their villains, including the A-Squad Rangers and Emperor Gruumm. The big new mechanic is 'Containment'—instead of just defeating villains, you can round them up and contain them to win. There are also stackable cards, which let you combine effects in cool ways. It's designed for 2-4 players, ages 14 and up, and games typically last 30 to 70 minutes. You'll need the core set (or the Zeo expansion) to play, as this isn't a standalone game. The theme is all about the galactic police force defending Earth, so if you're a Power Rangers fan, especially of the S.P.D. series, you'll love the artwork and references. It adds variety, new strategies, and keeps the gameplay fresh. Components are quality, and the rules are easy to pick up if you're familiar with deck-builders. A great way to expand your game nights with some cooperative or competitive superhero action.
