Among the Ruins
UPDATE: I fixed the requirement problem so you can now make hydralisks. Sadly, burrow is still greyed out, but you don't really need it anyway.
This is a remake of the firt mission of the Zerg campaign. I used a very old map someone else made during the early stages of the beta to make this, but don't worry, it works fine. Original audio dialogue is present, with an Overlord portrait as Daggoth and an Overseer portrait as Zasz. Tech tree limitations are in place. The Roach Warren has been removed and the Hydralisk Den set in it's place.
Ok, I fixed it. Thanks!
Well for the hydralisk den it's pretty easy, you change the "have lair" requirement to "have spawning pool".
I have found however it's difficult to remove requirements from something rather than change it into something else, so what i'd suggest for burrow is create a new requirement and keep it blank and use that for burrow research.
im sorry dude, idk on how to help you, but the idea of redoing the sc missions are awsome!
