They all were kind a training maps - with growing difficulty.
Started with 1-2 unit on map, ended up with more - and bots from end are more "skilled".
At list for me fight with Klesk on nightmere was break point ))
Also, the name of the tiers:
1 - training;
2 - skill;
3 - combat
4 - warrior
5 - federate???
6 - master
7 - elitehttp://www.youtube.com/watch?v=Gvn4VHTnmFI
Like - first you train, then you gain a little bit skill, then you're let to real combat; and only then you can be counted as a warrior. ))) Just IMO.
Btw why can't remakes be used?
