A spot of light entertainment is proffered by the 'Acceleration Suit', whose power charges gradually with kills, releasing a burst of speed and increased firepower for a few seconds. You don't really need it, though. In fact, you don't really need anything on offer here at all. If your progeny are really screaming for a slice of the playground kudos, then get them a copy of Viva Pinata and Sellotape a generic action figure to the front of it. They'll thank you for it later.
