3-faced snakes...? Are you talking about the Hydra?

Also, unfortunately, it seems that the model viewer is no longer being developed due to the pain in the ass nature to update it. I think whoever was working on it ragequit over gear colorations and alterations.

I haven't gotten to do any BC due to the fact I've been working on leveling classes on my alt (who's kind of become my main), but can you elaborate on what you mean? Do you think the Bio-labs are associated with the Garleans rebooting them, or are they clearly not involved with BC2?
