AHHHHHHHHHHHHHHHHHHHH!
GOOSEBUMPS GOOSEBUMPS! GET IT AWAY! AAAAH!
I would HATE that in Tremulous. Don't want to get goosebumps everytime I attack alien base you know!
shudder
That'll give people goosebumps? Really?! THEN YES YES YES! WE NEED THIS FEATURE! When I play as aliens I want to FEEL like an alien, and that means (aside from choppers hudmodels) a base made from thick slimy organic-looking material that oozes mucus and relentlessly consumes and infests everything in it's range.
Seriously though, I'd really like this. Perhaps have the tiled creep (as suggested by Odin above) spread between eggs/om and dependent structures, or just have it spread between structures that are within a certain range of each other. If this were to happen slowly then you'd get the "slow infestation" effect where the alien base would become progressively more slimed over time.
Isolated structures would just have the normal creep root else it'd be difficult to hide eggs.
Mmmmm... sliiiime.... mmmmmm
