Fancy letting off some steam and furiously thumping anything that moves? Portal Defenders has the answer! The aim is to fight doggedly to beat series of enemies and bosses as they emerge from portals. Perform combos and series of blows, use bombs to get you out of sticky situations and eat your enemies’ organs to push those energy levels back up. You only have 1 life to complete the entire game, so there’s no room for error!
