DualShock Nexus: From Twenty Four Caret Games comes a new type of rhythm game. Retro/Grade is a rhythm based space shooter with a twist; everything in this game goes in reverse. Along with several power-ups, levels, and a ton of unlockable ships, Retro/Grade should provide players with a lot of replay value. The concept itself is great, but like any rhythm game; it either needs a high fun factor, challenging gameplay, or a nice mix of both. Let's see if this technical rhythm title is worth checking out in our review of Retro/Grade.
