I have to say that I've been pretty hooked on this game, and I rated this a 9 because I feel as though this version has stuff I remember from the PS2 version so, I'll get started on what I have to say. The graphics aren't that bad for a first person shooter game with its visuals and gun detail. The sound has it for the GBA, most of the sound that's from the PS2 version is on this version too. Like I said, I've been pretty hooked on this game for the addictiveness it has, I do like how they tried to make it like the other versions. The story is pretty much the same as PS2, but I feel as though there are some stages that are missing but, that's just me. The depth of it is ok, it has a wide selection of weapons but what would have made it more interesting is if it had multiplayer so that you could shoot it out with your friends without having to look at each others screens. The difficulty depends on what mission your on and it does take some time to get used to the stages if not some memorizing. In conclusion, it's a pretty nice game for the GBA, I actually wish I had a physical copy of the game to bring with me when I'm out somewhere like, school.
