The 4 in 1 Action Pack is a collection of four downloadable PS3 games on a single disc. Mushroom Wars is a pared-down real-time strategy game with a focus on small-map skirmishes. Smash Cars is a 3D racer featuring RC vehicles and exaggerated, kart-style action. Digger HD is a single-screen action game, (unofficially) based on the arcade classic Dig Dug. In Wakeboarding HD, an ace boarder performs tricks on realistic waves. Produced by Creat Studios and TikGames, all four games in the collection were originally available on the PlayStation Network. ~ T.J. Deci, All Game Guide
