Abyss review. Classic Game Room presents a CGR Undertow review of Abyss on the DSi Shop for the Nintendo DSi and 3DS developed and published by EnjoyUp Games. The year is 3024, and mankind has wiped the Earth clean of its natural resources. With its survival at risk, the human race looks to the planet's last virgin territory for energy—the bottom of the ocean. Controlling a fragile biomechanical robot named Nep2no, you have to collect light-giving energy sources tucked deep into the ocean's caverns. Abyss is essentially the arcade classic Lunar Lander combined with the water level from Teenage Mutant Ninja Turtles for the NES. Weird, right? This video review features video gameplay footage of Abyss on the DSi Shop for the Nintendo DSi and 3DS and audio commentary from Classic Game Room's Derek.
