Browse to your MW2players directory. Note that it’s not MW2players for all people. Search config.cfg in your c:documents and settings folder, and you should find the config file. Open config.cfg in wordpad and add the following lines:
set developer “1? set sv_cheats “1? set thereisacow “1337? bind M “cg_fov 90?
Once ingame press M to increase your FOV. You can also change “90? to whatever FOV you prefer. Optionally, if you don’t want to have to remember to press M to set your FOV, locate the line ‘bind W “+forward”‘ and change it to: bind W “+forward;cg_fov 90? This will set your fov automatically as soon as you walk in each level.
Changing FOV in config_mp.cfg is untested, but it may work (no idea if this is detected by VAC).
