Excellent map 3 hours trying hard
Good map :)

@Maxson Best of luck on Hard difficulty, expansion to as many garrisons help a lot as well as fire bases to deal with the infantry (before pathfinders) since they are notorious for diverting EMP fire

MEDIUM / NORMAL level difficulty - BEATEN. I did few tries and eventually was able to push him out of the base, the strategy that worked out for me was to hold him in 2 major routes, from the north east and east, luckly for me he stoped attacking from north-west if you concentrate production and forces only on these 2 routes. I strongly suggest anyone to invest in secondary economy after 2-3 mins of game and constantly almost spam missile defenders. Good map overall. Gonna try to beat him on HARD now.

EASY level - simple, was able to rebuild entire base (half of the map basically) and push further. I think there a bug, after a while he just doesn't attack (when you have advantage in manpower and control of the map). The nuke is easily countered with Aurora Alpha's. 4 planes - nuke gone, gives you a window in 2-3 mins to prepare better until he rebuilds again. Progressive increase in attacks, flank attacks with MIG's / Helixes groups are noticeable too.
MEDIUM / NORMAL level - quite challenging, wasn't able to beat him (yet, skill issue on my part). Everything from above + Heroic Emperors rush makes a difference VERY noticeable. The attacks are non-stop and hard, especially when secondary economy hasn't been built enough.
HARD level - didn't tried yet, until beat normal. (I believe it's the hardest possible with a ton of heroic level units constantly rushing on all directions and up to 5 nukes at full force).
Thank you for the map.

too difficult on easy ,needs a bit more time to set up defences
