STP: Zombies. It had to be zombies. At first glance, Spooky Xmas looks like your run-of-the-mill tower defense game. You actively defend your samurai character’s dojo from an oncoming horde of the undead who are decidedly filled with holiday cheer. As zombie-related titles go, having them dressed in ugly Christmas sweaters and attacking you from reindeer-drawn sleighs is probably one of the highlights of the entire zombies-in-games tropes.
