Acheron Prime review. Classic Game Room presents a CGRundertow review of Acheron Prime from InsurgentX Entertainment for the iPhone. Acheron Prime is an atypical game for the iPhone in that it's far deeper and more involved than most iOS games, The game is a weird hybrid of space shooter and RPG. You play as a space captain with a lost memory and a cybernetic chip implanted in her head. So you're actually a cyborg. Helluva thing to wake up to. Acheron Prime has lots of polish, nice graphics, even voice acting. This video review features video gameplay footage of Acheron Prime for the iPhone and audio commentary from Classic Game Room's Derek.
