A fast coop map, that needs ptience and tactic.
Here you need to kill all warmachines of AI before it´s army come to kill yours.
Here is NECESSARY to build jammers and move them close to your warmachines; put all your units in center, because with it, you can create a iron defense; kill planes( rpators and condor bombers ) before all other ´´common´´ units, because they do a lot of damage against your units; as in map called Going Gold, here have stealths too, in south, west and east (!), so NEVER put your warmachine without a good defense against stealth tanks; don´t worry about warmachines in south, because they will fastly be killed, so build a strong unit to do a lot of damage against AI´s army (an annihilator is nice for this job).
SPOILER: The following image reveals all Stealth Tanks that are in map (due to not being able to get coop map files, i am unable to show the exact Stealth Tank units positions, so, how they appear on the following image is just a conjecture, but i know the quantity thanks to videos i recorded while Battalion: Arena was still online/avaliable):
This page's improved info, map's image quality, organization and more details thanks to Machow8, since he datamined all games from Battalion: Series games.
