Do this for each weapon so you can see the upgrades available. This way you can get all the weapon upgrades after 1, 2, and 3 kills instead of 25, 50 and 100 kills. Now change the values for ExpPointsLevel1=, ExpPointsLevel2=, and ExpPointsLevel3= to 1, 2 and 3. Press Ctrl+F and enter 'ExpPointsLevel1=' without the quotation marks. Open the DefaultWeapon.ini located in the directory 'C:\Program Files\Electronic Arts\Medal of Honor Airborne\UnrealEngine3\MOHAGame\Config' with Notepad.
