Halli
The event will take place in an old training area of the Defense Forces called Halli. The area has plenty of roads, great terrain and good places for faction bases.
There are lots of good/wide roads in the area, as well as plenty of smaller forest roads. Due to the extensive road network, the game does not get stuck in one place, but almost always there is an option to hit the enemy from behind.
If you are thinking of getting an ingame vehicle, now is the right time!
Game area map
The map intentionally does not show faction specific tactical points. The capture and resource points locations might also change a bit during the event. You can always find the most up-to-date map during the game at status.ehasa.org.
