The hack ‘n’ slash Warriors series has been going for several years now and in its time Koei Tecmo have managed to add a good number of cross-over specials to their franchise. Previous cross-overs include the Japanese mecha series Gundam (Dynasty Warriors: Gundam), Nintendo’s epic Zelda franchise (Hyrule Warriors) and coming up is the Square Enix’s JRPG series Dragon Quest (Dragon Quest Heroes). Then there’s the epic pirate adventure; One Piece Pirate Warriors. This mix of Warriors massive scale fights with One Piece’s completely mad plot makes it a complete winner. Many times in the show you’ll see the straw hat crew mowing down wave after wave of enemies culminating in boss fights, so to actually do that gives fans a massive sense of satisfaction.
