These maps are all similar as in a straight two sided map of spawn locations like the third image. If you control it correctly and spread evenly, enemies will spawn on the other side everytime. Derail might not seem similar, but there are no spawns on either wooded areas so that leaves you with big warehouse, center building and train area only.
These are the four split sectioned type maps, if you can evenly control three of the sections, their stuck in the fourth.
These are just like two side maps, but wide ones. same rules apply, if your spread evenly with one guy in the back so nobody spawns behind you, their going to spawn on the other side of the map everytime.
Karachi deserves its own section because of its layout and results are reversed. You can actually force your entire team into one of the corners and still control the map. ergo: if everyones on "the roof" by the chicken coups, theres to many things in the way for enemies to see you before you see them and get the kill.
These maps follow the same ruleset as the four sectioned maps mentioned above, except more difficult because theres occasions of random spawn locations. ergo: an enemy can spawn next to you or right behind your team even with map control. Estate is a secret, its all about the wood pile, if you control the house you need atleast one person at the wood pile behind it or the game will eventually spawn someone back there. Underpass ive had someone spawn right infront of me a few times. It all depends on everyones locations, so the game will spit out a few "i dont know where the fuck to spawn you" locations.

*this only works when you run up against the wall. simple but very effective*
The following steps will enable you to remove the ambient sounds (gunshots and explosion sounds in the map background) ingame plus the annoying lobby music
NOTE: This will not get you banned, it is untracable and is seen as a missing file and thats all.
Locate the MILES folder in your modern warfare 2 or 3 directory, usually...
Steam\SteamApps\common\call of duty black ops\MILES
Open the folder and delete the contents and the ambient map sound is gone leaving you to hear enemies footsteps twice as good.
Verify game cache to reinstall, check it often it will fix itself at random sometimes so just delete the files again.
locate your cod:modern warefare 2 directory. steam:
steam\steamapps\common\call of duty modern warfare 2
locate iw4mp.exe
right click and select "Properties"
check the box for "Disable Desktop Composition" & optionally "Run This Program As Administrator
click Apply
click Ok
Thats it, now test it.
config_mp.cfg is the name of the file and is located usually...
steam\steamapps\common\call of duty modern warfare2\players
if you want to edit things manually.
it would be a good idea to set it to read-only when your done editing so mwf2 doesnt override anything.
