On map there will be entities that are called landmarks. When some part of gamemode need to describe the location as text it will grab the nearest landmark to location.
Once all tasks are completed game enters an end stage in which the team that completed all tasks will be chased throughout a map, if all team members get eliminated end game stage will be failed and the game will proceed.
Once anarchist completes all of his tasks he needs to go to a certain point on the map to grab some kind of an item then game end event starts. With the item he must run to the helicopter on the furthest end of the map. Every 30 or so seconds all players get hints to where the anarchist is using landmark system.
As teamkill is allowed there needs to be a system to punish players who kill their teammates. Hiders are the only team wich is both co-operative and allows teamkills. Players wich killed their teammate get exiled and get a bounty on their head. These players have no way to win a game except killing a seeker. Obviously team damage should be made togglable for use on public servers though if feature proves to be working well toggleability can be debated.
Theme is a background music that plays during interaction with seeker. If player spots seeker or other way around more quiet music will play. If they engage in a fight combat music will start. Theme system will work with these types of audio: start, loop and end. The blending will work as follows wait for the end of loop, play start sound and start the other loop.
