TSTOS 18 will be held in the Finnish Defence Forces training grounds area. The game area is located in Hattula not far away from Hämeenlinna.
The Game area suits well for this kind of big airsoft event because of its big size and good road network. There are Finnish defence forces buildings in the area that are fenced and marked as banned areas in the map. If you can see the fence, leave it immediately, so you do not cause an unnecessary alarm.
