First off I'd like to thank all MPGH Hackers for the hacks they've made,
Now this is a Topic for some commands I've been using to mod the game, some of you may know them, but others don't. It's also to answer choob questions (Yes I'm a choob too, oh the irony).
Host Codes
badhost_endgameifisuck 0
cg_scoreboardpingtext 1 (Ping with text, your ping should be >50 if you're host)
party_hostmigration 0
party_connecttimeout 1
Gametype
g_Gametype (Gametype)
gametypes are:
-dm (ffa)
-ctf
-gtnw (global thermal nuclear war, DLC)
-dd
-dom
-koth
-sd
-vip
-war
Interesting Codes
scr_thirdperson 0
scr_player_maxhealth 100 (possibly to change hp??)
scr_player_healthregentime 5
scr_nukeCancelMode 0 (cancels nuke)
scr_nukeTimer 10 (seconds til nuke goes boom)
scr_oldschool 0 (like in cod4???)
ui_hud_hardcore 0
scr_hardcore 0
scr_game_onlyheadshots 0 (headshots only like in pvt matches)
scr_game_perks 1 (disables perks)
splitscreen 0 (co-op or something?)
sv_voiceQuality 3
sv_zombietime 2 (possibly DLC ?)
timescale 1 (game speed?)
cg_footsteps 1 (hearing footsteps?)
cg_fov 65 (like in cod4)
com_maxfps 100
r_fullscreen 0 ( 1 to full 0 for windowed)
Common Questions
Q: Does the scr_xpscale command work?
A: NO!
Q: Can I set no killstreaks for everyone?
A: Not that I know of.
Q: Can I not be host and still do the previous?
A: Only Clientsided changes, anything that is server-sided won't work.
Kudos and Credits to the finders of these codes, and to the maker of the console command, I just made a help thread for choobs.
EDIT: All above values are DEFAULT! For example nuke_cancelmode 0 will not allowed you to cancel it, set it to nuke_cancelmode 1
0= off
1= on
