I decided to replay the IKSPQ series and I did find the button this time around. Frankly I think it would be better if it opened up a secret door rather than the intended path through the level. Aside from that, I think the castle is too cramped and the ammo supply to limited for the difficulty (on Hard), and it just doesn’t look nearly as good as the following maps in the series.

hahahaha in the screen shot…see it now 
OK, ummm, I killed everyone, found the 2 not-so-secrets, got the gold key but somehow I can’t seem to find the exit or any gold door. What am I missing ? And yes, I’ve found the button @ the tower that’s clearly not hard to find if you just look around a bit…

This time around, I had time to read the centerprint: for anyone else wondering, the start slipgate is also the exit. Go figure.

It’s quite a nice map with nicely detailed architecture. At times it felt a bit stingy on resources and cramped for both me and my enemies. But overall, a pretty solid experience, about a 3+ at that.
