i loved the original,but was let down by Halo 2(especially the campaign).
immediately(started with MP)i could see the controls were far more..."solid"....smooth?i dont know how to describe it,but i knew there was something special before even getting my first kill...just felt perfect.the sticky aim seems to have been toned way down(from Halo 2) as well,which was a huge plus.
havent played much campaign,but based on the first level and the multiplayer(havent even tried forge yet).
I dont know why halo3 got a 9.4 rating,i mean its AWESOME!Superb graphics,great gameplay,and cool weapons such as the gravity hammer which is my favorite weapon!I actually think the marines in halo3 are a lot smarter than the ones in halo and halo2.They hide behind things and take down most enemies pretty quickly.the new gadgets are cool too like that bubble thing and the regenerater.There are a few new vehicles too such as the new warthog which can carry 4 people and the choppers the new brutes have.I love the new multiplayer feature where you have up to 4 people on one screen and they are all different characters.The explosions and gun battles have improved since halo2.The bottom line:Halo3 is the best XBOX360 game that has come out(opinion).Have fun playing it!!
