So here we go:
- My copy of Keen 6 is pirated.
- I have never completed Weaponry B in Keen 2. That level seems entirely pointless and hard. (I've done everything else, though.)
- I have never completed Keen 3, and several levels I haven't completed.
- And up until a year ago, I had never completed Keen 2. Washington DC, they'll get you every time.
- I have never completed Keen Dreams, and there are several levels that I've not completed.
[Edit] Well, maybe I have completed Weaponry B, but it wasn't really noteworthy because I didn't go for any of the hard-to-get goodies.
