This story appeared in 2000AD (I think), about 8 - 10 years ago.
The main character was a woman police ofice with a mask that covered half her face.
The story was based around a corporation that was poisoning workers on mars. There were bizarre mutations and deaths due to a drug.
The story finished with a "to be continued" after quite a few episodes.
I've always wondered if they ever finished it.
Any help would be greatly appreciated!
Sounds like Mambo.
