Так как на просторах инэта, после смерти сайта автора, найти описание кваров GunGame попросту невозможно, вылаживаю их у себя:

Commands
amx_gungame <0|1>
Toggles the functionality of GunGame. Always use this to enable or disable GunGame in the middle of a map. Requires ADMIN_CVAR (or flag "g") access to use.
amx_gungame_level <target> <level>
Changes a player's level. Target can be a player name, *, @ALL, @TERRORIST, or @CT. If level is prepended with a plus or minus symbol, the level change is relative. Otherwise, the level change is absolute. Requires ADMIN_BAN (or flag "d") access to use.
amx_gungame_score <target> <score> [dont_refill]
Sets a player's score. Target can be a player name, *, @ALL, @TERRORIST, or @CT. If score is prepended with a plus or minus symbol, the score change is relative. Otherwise, the score change is absolute. Set dont_refill to not refill a player's ammo and armor. Requires ADMIN_BAN (or flag "d") access to use.
amx_gungame_vote [mode]
Starts a vote to enable or disable GunGame. Requires ADMIN_VOTE (or flag "j") access to use.
amx_gungame_win [target]
Forces target to win. If no target is provided, the best player will be chosen (sorted by highest level, then highest kills, then least deaths). Requires ADMIN_BAN (or flag "d") access to use.
amx_gungame_teamplay <0|1> [killsperlvl] [suicidepenalty]
Toggles teamplay mode. You can optionally specify new cvar values for gg_killsperlvl and gg_suicidepenalty. Requires ADMIN_BAN (or flag "d") access to use.
amx_gungame_restart [delay] [full]
Restarts GunGame. You can optionally specify a delay, in seconds. If full, reloads config and everything. Requires ADMIN_BAN (or flag "d") access to use.
gg_reloadweapons
Reloads the weapon order and the kills per level from the cvars. This must be used if either of those two things are changed mid-game. Can only be called by server.
