Battlefield 2 is like counter strike. Cheat battlefield 2, you can read step by step at this blog :

All weapons battlefield :
Use a text editor to edit the "unlocks.py" file in the "pythonbf2stats" folder.
Change line 44 from "defaultUnlocks = [0, 0, 0, 0, 0, 0, 0]" to "
defaultUnlocks = [1, 1, 1, 1, 1, 1, 1]".

Easy scoring battlefield :
Note: This procedure involves editing a game file; create a backup copy of the file before proceeding. Use a text editor to edit the "scoringCommon.py" in the "\ea games\battlefield 2\mods\bf2\python\game\" folder. In this file you will see score list for different events, which can be changed as desired. Be careful, as it also works for enemy soldiers.

example:
SCORE_KILL = 50
SCORE_TEAMKILL = 40

The same thing can be done for the "gpm_cq.py" file in the "ea games\battlefield 2\mods\bf2\python\game\gamemodes" folder.

example:
TAKEOVERTYPE_CAPTURE = 100
TAKEOVERTYPE_NEUTRALIZE = 200

Easy points battlefield :
When you have a certain amount of points on the game, keep getting more. When the end of a round is near, switch to the winning team and your score will be doubled.
