Not sure there's any commands that specifically have "-vote" in it but there are commands in which majority votes are required to pass.
Single commands:-c 150 l s (c => Camera, 150 => Zoom amount (generally around 120-180), l => Lock which locks the position, s (optional) => Scroll on. Basically smooths the scrolling around the map)
Note: This command can be used alone and requires no vote as all it does is adjust your camera/scrolling to your convenience for better gaming experience.
Vote commands:-exp => Requires majority of builders to pass, will give titan double exp rate on all units/structures it kills.
-froff => Same as above, only will disable feed reduction rate of titan. (Meaning, it gains the same level of exp for nuking workers each time, instead of going down)
-gc => Same as above, only will give titan "Gold Coin" which randomly drops a gold coin if a titan kills a structure. (Both titans/builders alike are able to pick them up and gain 1g)
-ar => Beginning game command, requires both titan and builder majority to pass. Will issue the game all random for both builders and titan.
-ap => Beginning game command, currently disabled/broken but was suppose to allow multiple picking of various builders if turned on.
-up => Default game mode, will make the game unique in the sense that only 1 builder each can be picked. If people vote for this in the beginning, it means they want the same mode to stay.
Bot/vote commands:!votekick (username) => Will start a votekick on a player. If majority say !yes within the time given, the player in question will be kicked from the game.
Note: This command is to only be used against people violating ENT rules/ruining the game. More info on that can be found
here.
Note2: This command is provided by ENT and holds no affiliation to the map.
