Plus, if one has fallen, and I revive him, does that mean I won't get the achievement? Weird one.
No you won't mate. I've been doing the good campaign this week and have finished it with all the extras done. On the last level I clicked my fortress only to my horror to see that I can revive a hero. I did this and then finished the game. No achievement!!!!! Bollox, i've started from scratch again!
Nice tip though looking in the stats at the end to make sure. A great idea
