Answer
Once you get X-Box LIVE or for PS3 you just connect to the Internet and go on. After you get the update downloaded you go to multiplayer and you can go to LIVE or what ever it says for PS3 and click on Combat training, or, if you no longer are connected to the Internet you can go to Local and be able to choose how many Bots(enemies/friends) are playing. Haven't played the game in a while so I forget.
Sadly, you can not. BUT you can play offline bots with 2 people.
No, but it has offline bots.
Go to the local in multiplayer then where it says set up bots click there then but how many friendly bots or enemy bots you want then set the difficulty to whatever you want
You can not play combat training offline.
you dont need live to play bots go into multi playr and go into the options to use bots.
You can only buy it online. But you can play the maps offline there after.
no
some of it and some not
Yes.
The only way you can actually go up against bots in Modern Warfare 3; is to play Survival or Chaos modes. MW3 does not possess 'Combat Training' (ref. Black Ops) or Local Play (ref. Black Ops 2). Another way is to do the SpecOp missions at the differing level of difficulty.
No
If you're offline, you're not connected to anyone but your own console, so you can't play multiplayer.
