When Vikings! Attack is a fast paced brawler from Clever Beans. In it, the player controls a mob of people, and sets out to defeat other mobs by throwing items at them. It features a 15 level quest mode where the player is tasked with saving a vaguely 1970s British town from rampaging Vikings, and various multiplayer modes with up to 4 players local or online across both PS3s and Vitas.
The gameplay consists the player of growing his mob of people by collecting neutral individuals, while depleting his opponents mob by throwing items at it. The larger a mob, the larger the items it can throw, however as a mob grows it also moves slower. When faced with an incoming projectile, the player can dash away, or attempt to catch it. However players also have the option to charge up their throws, making the object unstoppable.
