ANYONE CAN PLAY: the dynamic adjustment of the difficulty levels in the game makes Ion Assault HD as easy for beginners as it is challenging for experienced players: the faster the player can clear obstacles out of the way, the more enemies will appear and try to thwart his plans. The player can also decide if he wants to carefully clear any obstacles from his path or, if some racier battle action is required, see how many enemies the game can throw at him.
