The Pac-Man spin-off Shadow Labyrinth is getting a nice discount for Prime Big Deal Days. The standard edition on PS5 and Switch is down to just $20 (was $30), while the Secret Edition with its physical collectibles is just $40 (was $60). The sidescrolling metroidvania gives you a chance to see the yellow puck in a whole new light--or shadow, as it were--and since these are the lowest prices we've ever seen for the game, it's a good time to finally check out this wild reimagining of one of gaming's most famous mascots. The discounts will last until the Prime Big Deal Days event ends on October 8.Shadow Labyrinth Secret EditionShadow Labyrinth released on July 18, and while it's earned polarizing reviews from critics due to its ideosyncratic mix of Metroid-style exploratory action and Pac-Man-inspired puzzles, it's no doubt one of the biggest metroidvania-style platformers of recent memory. It's also part of Bandai Namco's infamous "UGSF" crossover universe that includes Galaga, Galaxian, Dig-Dug, Mr. Driller, and even Ace Combat 3 as canon entries--which means fans of classic Bandai Namco series can expect plenty of easter eggs and in-universe references to all those games and more. Looking for more metroidvanias? You'll find a digital code for Hollow Knight: Silksong on sale at Amazon as well. The highly anticipated game has lived up to the hype--though many find it to be remarkably difficult, thanks to punishing bosses and tricky environmental hazards.For additional Pac-Man gear, check out the vibrant Arcade1Up Pac-Man Deluxe Arcade Machine.
