Yes I know, you're getting sick hearing from me about my scenario fettish
. The moderators are going to ban me out of annoyance pretty soon. Until then, here's a hard one:
Basically, you are in a bad spot, and only have one turn to make it better. You have a variety of units, and you need to use every one of them in the first round to try to take an enemy ally. If you fail in the first round, the enemy will have reinforcements, and will walk all over you.
If any of you have ever played the Magic card game, you know that there are as many rules as there are different card types. I based this scenario off a magazine that made Magic puzzles: You would see a specific layout of cards, and you would try to figure out how to kill the opponent this turn. They could be quite difficult. Same idea here. You have to figure out how to manuever your units to kill all the enemies in a territory this turn.
I revised this scenario... the new version can be found further in this thread.
