The consoles and PC version might be a bit passable but this one is quite awful.
In X-men the official game you get to play has Wolverine, Nightcrawler, Colossus and Iceman. Starting off the problem here is that they barely do any difference in the game unlike the console version. Wolverine pretty much slashes and beats up enemies like always and has the ability to heal. Pretty much exactly what he does on the consoles version. However in the GBA version you switch characters. Colossus pretty much has the ability to defeat the stronger objects. Iceman does his freezing thing and nightcrawler can teleport through walls. Yet you would only want to play with wolverine since he can heal. You do some walking here and there but is mostly taking out all enemies and obstacles that get in your way.
Graphically is also quite mediocre here too. The characters sure look pretty ugly not also mentioning how plain the background looks and how uninteresting the enviroments are. Is hard to say something really good about the graphics. Even tough they did a nice try to bring the x-men movie characters look on 2-D it still could have been better. Oh well Colossus is perhaps the best looking one. Audio pretty much features common soundtracks of most 2-D games with nothing really interesting on the mix.
Overall X-men the last stand is quite awful with repetitive bland gameplay, poor 2-D graphics and no special audio it becomes another game deserved to be on the list of crappy games out there. This is really hard to recommend you could only rent it if you like X-men and there is absolutely nothing better at the renting store.
