This Tactical Ops 3.4 server has all the 2200+ maps available for voting so players have an easy way to play, test or explore all preserved maps in the file archive.
It uses the MapVoteUL v2.4 mapvote mutator since it is the only one that supports up to 4096 maps. It has a very useful Search Function that helps greatly when searching a specific map, the only downside of MapVoteUL is it requires a minimum screen resolution of 1024×768 or 1280×720 to display correctly.
The mapvote has the ability to show map screenshots if a map has one, but it requires the map files to be present in your game folder or downloaded in the Cache folder. So it more or less functions as a way to see if you have played a map before or not.
For mapvote instructions read the Message of the Day in the server (F2) or view this YouTube Video.
All unplayable maps not on the server can be viewed here, or from within the mapvote by clicking the “Info” Tab at the top, then “Server Info” button at the bottom.
