Previous tests were at 800m x 800m. Now this stage involves testing at the maximum Random Battle size of one kilometre square. This is being done to test game play for the more mobile vehicles. Also in this test the number of paths between buildings is being reduced to limit close range rapid flanking. This is in an attempt to prevent one team just rolling over the other too quickly. The additional space on the map edges will give long range firing points for mobile tanks (light tanks) to control (lock down) points on the map.
Further testing may be needed but if all tests are succesful the map is destined for the random battle rotation.
