Free For All
A game where everybody is on their own team trying to kill each other. This game a silenced gun is a must. You go up to two hundred fifty points, but with ten points a kill that's the first person to kill twenty-five people. To master the game mode the gun options are numerous, so pick one that works for you. The majority of the maps will have a different gun that will work best. Usually if you have the overkill perk picking a silenced M16 and a M4 or P90 will lead you to a successful game. The M16's iron sights can easily pick off others, while the M4 or P90 are at your disposal for close quarters situations in the game. If you don't have the overkill perk go with the M16 or M4. You will receive decent points in this game for the amount of time a game lasts, but I still do not see this as a feasible way to bring your rank up as you get higher. Once again this is a game mode that is probably more for fun than for actual experience points.
Team Deathmatch
Team deathmatch is by far the most populated game variant on Call of Duty 4. It's straight up combat with no objectives other than to kill the opposing team. You can walk wherever you want with no need to spring across the map in a hurry. This leads to the danger of many helicopters and air strikes though. Increased number of campers than in other game modes, but it does give a more real life game situation. You receive ten experience points per kill, and a match bonus at the end. This is a quicker game to play, yet the winning team can only get seventy-five kills, which leads to virtually no experience points. Play this game mode for fun, as it's not going to help you raise your ranking that much when you get into the higher levels.
Search and Destroy
Much like a Counter-Strike bomb game, there is one bomb and two places to place it. One team tries to defend both places, while the other team tries to plant the bomb. There is no respawns in this game, so once you die, you are out for the round. This can lead to a tough choice on what gun to use. The answer is not an easy one. The gun you should use totally depends on the map. A good gun if you don't have the overkill would be the M4. Many guns will be more effective on different maps so you'll have to experiment with them. You get fifty points for a kill, and one hundred points for either arming or defusing the bomb. This is a great way to earn points because you can earn five times the amount of points per kill than in deathmatch, and ten times what you get in headquarters.
Team Domination
Team domination is a very busy game. You have several flags across the map that you must capture, and defend. Your team scores points based on how many flags you're holding for a certain length of time. You score goes up quicker when more flags are held than the other team and slower when you have fewer. You get experience points based on kills, five points each, capturing a flag, and then the points your team gets for holding them are also counted as experience for you. Decent game mode if you can get a few good streaks going to get a helicopter and air strike. Keys things to do would be to defend a flag in the middle from an area you cannot get shot. So you should either camp a good distance away with a sniper, or nearby with a mini machine gun or other automatic gun with medium range.
Sabotage
Sabotage is a very fast paced game mode. It is very similar to search and destroy as there is only one bomb and it must be armed on the enemy's base. The difference is it's a neutral bomb and you must fight to keep them from arming it at your base while trying to bring it to theirs. A lot of back and forth action that can lead to some long, fun games yet it is a rather simple objective. The gun you would use is completely dependant upon the map and the role you decide you would like to play. If you plan on defending you may want an M203, but if you plan to attack you would want an M4, MP5, or shotgun. It is pretty easy to get kills in this as there are unlimited respawns yet you get a pretty long respawns time. Five points a kill, one hundred for arming or disarming a bomb. It's pretty easy to learn, and a great way to experience.
