Updated 21sep2017 (version 1.7): more ore, more building space, etc. You can delete the older version (1.3) in your game folder if you have it.
Survival map called Hazz. Hard AI. You have to defend your base against AI's waves of attacks for 20min. It is recommended to be played 3 humans vs 1 AI (Russia) or 3 humans vs 1 human (Russia), AI will still play and attack the non-Russia players and be controllable by the Russia playing human.
This map is originally made by ZiiP and called Hazzardzone. I remade it a bit. Now is the AI significantly stronger and there is naval bay.
In order to not get startup error, you have to a) be 4 players in total, AI or human b) select one country each of America, Germany, Great Britain, Russia, with no country doubles or other countries c) AI must always be Russia in soloplay. A human can play Russia in multiplayer mode against other humans which makes him able to control the AI's attacking army.
