Thundercats video review. Classic Game Room presents a CGRundertow video review of Thundercats from Aspect Digital Entertainment and Namco Bandai for the Nintendo DS. Based on the 80s cartoon, Thundercats is a rudimentary 2D brawler that puts you in the role of Lion-O, the leader of the Thundercats. Lion-O can jump, though not particularly well, and swing his sword at enemies who all look the same. The game is slow and cumbersome, and the gameplay gets repetitive really quickly. This is not a good beat 'em up. This video review features video gameplay footage of Thundercats for the Nintendo DS and audio commentary from Classic Game Room's Derek.
