Hope u like it, now I suggest for mission 6 (limited gold) that you save all up all your research points for this mission, coz without an option to reset skills you should have all possibilities open. Everytime you start, you can spend all pts so far on different skills until u beat it.
Has anyone beaten the game on extreme, hardcore, tactical difficulty (281%) yet?
Because I just beat the corruptor :) Here's a pic:

As you can see, I killed all except one boss on level 4. (The resulting exploration of 88% results only because I'm standing on the first room of the still unexplored 10th level)
