NO DVARS NEEDED!!
So I Just found a cool thingy in _airdrop.gsc so you can edit % or like emp drop rate or even a nuke!
1.First Make a folder where you put the _airdrop.gsc file in (i dont remember the folder name cuz i am on another pc )
2.Make a gsc named _airdrop.gsc.
3.Go to #include maps\mp\_utility; #i - Anonymous - 8x24aM46 - Pastebin.com (Thanks to Master for the GSC Rip )
4.Copy Evrything in thecode ant put it in _airdrops.gsc file you made.
5.Open The _airdrop.gsc file
6.Find init() ( lol you can see it already )
7.Find The 87 Line, 88-101 lines are normal care pacage,103-117 are the emergency air drops .
8.Edit What You Want. Example
addCrateType( "airdrop", "ammo", getDvarInt( "scr_airdrop_ammo", THE % OF THE DROP RATE HERE ), ::ammoCrateThink );
Btw I Havent Tested This Cuz I Dont Have MW2 For A Day So I Need Testers!
