Oh... I loved the idea of that mod, of vehicles with weapon like short range artillery, like 90 or 120 range. I am playing with frost biters, explosive biters, toxic biters, and the aai vehicles and yours all die in 0,5 seconds when I try to enter a cluster of spawners. Even the maus and the ratthe die like in 1.5 seconds. So not worth using vehicles against these modded biters. That is why I loved xenos. There was several vehicle-artillery or long range missiles that helped a slow advancement toward the enemy.
