Just figured this out and thought you guys might want to know it
1. Open your config_mp (C:\Program Files\Steam\steamapps\common\call of duty modern warfare 2\players\config_mp.cfg)
2. Add a line with this form:
[php]BIND <key> "<dvar>"[/php]
Examples:
[php]
bind , "map_restart"
bind . "fast_restart"
bind L "say \"^1INTERVENTION ONLY\""
bind I "say \"^1SPAWN SNIPING = KICK\""
bind O "timescale 0.2"
bind P "timescale 1"[/php]
3. Save the file and open MW2
(You will still have to be host)
Only client vars will work if you are not the host such as
[php]bind v "r_znear 100"[/php]
More examples:
[php]
bind KP_HOME "map mp_nightshift"
bind KP_UPARROW "map mp_subbase"
bind KP_PGUP "map mp_terminal"
bind KP_LEFTARROW "map mp_quarry"
bind KP_5 "map mp_rust"
bind KP_RIGHTARROW "map mp_boneyard"
bind KP_END "map mp_favela"
bind KP_DOWNARROW "map mp_highrise"
bind KP_PGDN "map mp_invasion"
bind KP_INS "map mp_afghan"
bind KP_DEL "map mp_brecourt"[/php]
(This binds every key from 0 to 9 + the , button on your keypad to switch maps)
This is NOT bannable!
