Any I'm missing that are classics?

Phobos Encounter by Razor Blade (now Kyouryuu) to which Mandrill was the sequel.

There was something called the Omicron Project for D2... but I never played it, and hence am not sure how good it was.

There was also an original Encounter at Farpoint SP mission - again, never played it, not sure on quality, but the levels were made by the same guy (Kam Sheffield, if memory from about four years ago is still as good). Very good designer.

well, I'm adding Phobos Encounter to D2 list, tell me which Descent the first EAF was and I'll add that too. But I've played the Omicron project and it didn't impress me much to call it a 'classic.'

The last time I played EAF, I was unable to finish it because the last level seemed to be more than a bit bugged. I may have gotten a bad version though.

It was for D2, BTW.

cool
