I set a scenario against multiple AIs on the large metal map. The only way to survive was to quickly construct barriers between the buildings to seal off your base because the AIs weren't programmed to destroy barriers. Then came the job of hunting down the AI commanders (I played killing the commander kills all of his units otherwise it was impossible to win).

Great game!

I got the largest metal map and created a basically impenetrable base, and then left the game running overnight.

It turned into a huge battle between the highest level of units and it was so much fun, but even then the AI wasn't extremely challenging.
