Imagine DOOM only watered down and less barbaric.
On the positive side it controls well enough and although the weapons aren't highly imaginative they're actually fun to use. The levels are also expansive and well thought out making it for a week or two worth of gameplay. However, the flaws unfortunatly drag it down significantly. The enemies aren't that well designed and the artificial intellegence is just as pathetic as the sounds they make. They're also remarkably easy to kill, even if you only use your pistol. Even if you play it on hard mode with about twenty five enemies in the room you could easilly take them all down without breaking a sweat. Where's the challenge?
All in all, Dark Arena had it's moments but there are a lot better games on the GBA.
