Here comes another platform feature for Tanks DLC to have fun with :) Our passionate programmers have added an option to switch the fire modes when using missile launchers, bombs, etc. And more importantly, added few different ways in which the missile can reach its target. 

In short - you can now switch the missile's flight from a simple direct trajectory to one that better utilizes the tank's weaker armour - e.g. the notorious Top attack. We'll try to add more info as the time flies and as the features get utilized more by the game's assets. As well as we'll update the documentation so you can try out what's under the black box.
