I worked on a commercial addon for Blood called Cryptic Passage.
Wow, so cool. To a Blood fan like me, you're a legend ;)
Unless you're a big Blood fan you might not have heard of it, but I worked on an addon called 'Gods', which quite a few people seemed to enjoy. It was designed to be the hardest bunch of levels ever created. We were going to make Gods 2 for Blood 2, but the editor for B2 was a tad underdone. I still have some original voices for it by Stephan Weyte (the voice of Caleb) that Monolith did for us while recording the stuff for the Nightmare levels expansion.
Good times...
I still hang out on the Blood forum, and have been there since Blood 2 was announced. There's not much to see there now though... the spammers have finally found it. I also did some work on Planetblood.com... so hearing about Blood now is like a sweet trip down memory lane :)
Ah, the wonders of Blood's multiplayer...
