Space Invaders review. Classic Game Room presents a CGRundertow review of Space Invaders for Playstation 1. The game is a great example of what a remake should be: an updating of a game but keeping the core gameplay the same. This maintains the classic Space Invaders gameplay, moving from side to side to take out descending space aliens. But with the additions of special attacks and boss battles, the game takes Space Invaders into the 3D age with style. This video review features video gameplay footage of Space Invaders for Playstation 1 and audio commentary from Classic Game Room's Ryan.
