I guess it’s alright. It's the first FPS I played on a handheld like this and I was surprised to find the controls pretty comfortable. The weapons are okay enough, and while the story is kind of cool, it feels a bit underdeveloped. The worst thing about the game for me is the repetitiveness of the gameplay, you're basically always doing the same thing with little variety in the puzzles and just general flow of the game, it doesn't feel very interesting.
