If your talking about multiplayer, you can't. If you are talking about offlline you just go into game setup or whatever and it should be in there..
you can do this if your doing a custom match like combat training or private match select game options and you can change the time limit
you will have to go to team deathmatch and open up the options, it will show a time limit and the number of opponents you want against and some other crap.
You can't. Beacause 2+2=4.
