Planets Under Attack video review. Classic Game Room presents a CGRundertow video review of Planets Under Attack, a downloadable game from Targem Games on the Xbox Live Arcade for the Xbox 360. Planets Under Attack is a game that hides nothing. Planets are under attack. You're a space traveller guy buried beneath such spectacular debts, the debt collectors occasionally shoot you with lasers and try to destroy entire planets. This is a strategy game with a simple objective—occupy as many worlds as possible. This video review features video gameplay footage of Planets Under Attack for the Xbox 360 and audio commentary from Classic Game Room's Derek.
