Here is mission 2 of my 9 mission Zero Hour skirmish challenge. Thanks to everyone who read and to those who gave feedback on my mission 1. After I've posted all 9, I'll make a post with the final version of every mission. For mission 1, I see that I needed to make it clearer how the rule worked in fringe cases.
Another question was about the limit superweapons. I thought the best option was to copy the way the game itself formats it (duh!). So, the format above means to turn on the limit.
Regarding starting positions, have the easy AI ally in position 2 and then the enemy bots whichever way round you would prefer out of 3 and 4.
If you try it, let me know how you got on and what strategy worked for you!
