Ultimately Halo 4 just feels aimless, there's cool ideas sprinkled throughout the campaign but they're often overshadowed by boring levels or a story that convoluted itself with new characters that drag down what could've been a cool dynamic with Cortana experiencing Rampancy, but they don't really do that much with it sadly. Combat feels very different from Halo 1-3, you have much less ammo in reserves and enemies are much more defensive, teleporting behind cover and regaining their shields, its just very frustrating if played solo, this problem felt less pronounced when playing the campaign in co-op . Vehicles feel useless in many cases because of how small arenas are, and enemies use charged plasma shots SO much so you'll just end up getting sent into a ravine or killed. The art design is really desaturated too, readability of enemy ranks using their armor color is basically impossible in a firefight. I don't recommend this game to anyone except Halo fans who want to play all of the games just out of curiosity.
