SP review only,
This review is from: Call of Duty: Modern Warfare 3 (PS3) (Video Game)
This is an SP review only as I stopped playing the MP when MW2 came out and it was a load of people running around with no sense of direction and no tactics. If you want MP reviews check out BFBC2.
The SP in this game is really good fun, intense and full of action. The weapons handle beautifully and the sounds are very good as well. There are no ridiculous scenes as there are in Black ops (which I gave up on) when wave after wave of Viet Cong flood in in the bunker scene.
There are no random respawns of enemies, once an area is cleared it remains cleared - no enemies suddenly reappearing ebhind you.
I played the SP very tactically and spent time choosing my position and shots and throughly enjoyed it to the point where I would happily play the game again on the more difficult settings.
If your looking for a good SP this beat BF3 SP, but the best MP is definitely BFBC2 then BF3 IMO.
Hope you enjoy it, I did.
