Arena (Game Gear)

This game is an isometric shooter, set in a dystopian future city. What's odd about this dystopia is that although the world is run by an evil TV station, the game isn't set in a deadly futuristic game show.
Arena came out fairly late in the Game Gear's life, and it shows in the graphics, which are of a much higher quality than you'd expect from the system. It's pretty fun, too. You run around the large stages, collecting keycards, killing enemies and trying to reach the exit. It actually feels a lot like an isometric version of one of the early first person shooters, like Wolfenstein 3D or Blake Stone.
The first few stages are set in and around a series of warehouses, and are fairly easy, though one strange thing is that the indoors areas are much bigger and more spacious than the outdoor ones. After you get through these, there's a stage set around a dirty polluted canal, and after this, more warehouses. Looking online, there does seem to be other settings for stages, but as the river stage takes a massive leap in difficulty, I always lose most of my lives there, and the remaining one or two a short way into the following stage. It's a shame, because until the game started sending enemies that took nearly 10 shots (with a powerful weapon, it would have been twice as many with the default gun) and can kill the player in two or three, I was really enjoying it.
So yeah, it starts off as a fun, nice looking game, but quickly gets killed by it's terrible difficulty curve.
