Calls an in-game vote for the next map near the end on the round. Randomly selects four maps (by default, can be adjusted) from the current maplist to vote on. Before the options are displayed, a banner can be shown to get the players attention that voting is about to commence.

The votes are tallied and if there are more votes than the set threshold, the winner is the map with the most votes. If there is a tie, the winner is selected at random from the tied maps. The next map is announced and it can be periodically displayed until the end of the round.
