It really depends on the gametype you are playing on
-->Team Deathmatch--> Is Simply a Standard game type where there are two teams and there is a timer or score limit that must be reached
-->Domination--> Domination is a capture the flag type game where the is Bases A, B and C. The objective is to dominate all three bases and reach a score limit which is usually 200
-->Search & Destroy--> Is like Elimination where every 3 (depending on server) rounds you swap positions from Defence to Attack.
The aim for Defence is to Guard the Bomb from the Attackers who need to plant the bomb or you could simply eliminate the other team.
However, the defence could not win by killing the other team completely if the bomb is planted so you must defuse the bomb. (it isn't as complicated as it may sound)
-->Free-For-All--> Simply a every-man-for-themself game type

Yes, there is online multiplayer on Call of Duty 4: Modern Warfare.
Call of Duty World at War, Modern Warfare, Modern Warfare 2, Black Ops, and Modern Warfare 3 all have online multiplayer.
Multiplayer is free.
Yes - multiplayer is free
Sadly, you cannot get gamer score points in CoD: 4 Modern Warfare Multiplayer.
I would say that Call of Duty: Modern Warfare 2 is better, because of the weapon selection, perk selection, graphics, gameplay - both multiplayer and singleplayer storyline, the killstreak reward selection, the offline multiplayer class customization feature, and the online multiplayer gameplay. Everything about Modern Warfare 2 is better. Except the price.
U go to multiplayer if no multiplayer u beat
Yes You Can
Unfortunately no, you can't play multiplayer on Call of Duty Modern Warfare 1 or on Call of Duty Modern Warfare 2 on the same screen. But on Call of Duty Modern Warfare 3 and Call of Duty Modern Warfare Black Ops you can play multiplayer on the same screen. There is an new Call of Duty Black Ops 2 coming out soon though, so I expect that to also have that feature, since its newer.
There are no cheats for Call of Duty: Modern Warfare 2 online multiplayer. There are glitches, but these are slowly being patched by Infinity Ward. There are also hacks, but these are more complicated to perform. Personally, I think hacks are pointless.
There are a total of 70 levels (ranks) in Modern Warfare 2 Multiplayer.
No you can't.
