The Walking Fortress is an ultimate introduced in the 13.0.0 update.
It appears to be a large, futuristic vehicle/artificial animal walking with 6 legs. It has two doors, some windows on the front and some windows on the back.
It moves around the battlefield and attacks enemies with laser cannons.
At this moment, ultimates like this are not in the game. It is expected that ultimates will be added to the game at some point due to the fact that the player is able to browse them in the clan fort section, and also in the clan storage, which is quite misleading. At the moment, it is unsure if an ultimate will be an ability used once per game, or if it will be constant.
- Two large quantities of this item can be found in Walking Fortresses, hence the name.
