hale_first_round (Default 0) - If it's 0, first round will be default arena.
hale_circuit_stun (Default 0) - Time, in seconds, for the Short Circuit to stun Hale.
hale_spec_force_boss (Default 0) - If 1, VSH will count spectators as normal players and will allow them to gain queue points, but they will also be forced to be Hale when their turn comes. If 0, spectators are ignored completely, gain no queue points, and will not be selected as Hale.
hale_enable_eureka (Default 0) - Set to 1 to allow the Eureka Effect in VSH.
hale_force_team (Default 0) - As explained in the Tips section above, determines which team Hale is placed on. Setting this to 0 causes Hale to be on a random team UNLESS the map is a vsh_ map, in which case he is always BLU. Setting it to 1 causes it to be completely random. Setting it to 2 causes Hale to be on RED all the time, and setting it to 3 causes Hale to be on BLU all the time. The default is 0.
