you can get them from some challenges, tournaments, & treasure hold boxes.Â
No, I doubt you can get any tower chematics from anthropus camps . You can not even get them from Crimson Citadels .
well sh*t
EDIT: Due to updates, I know that you can find the mystic tower chematics in the crimson citadels. Then, you MAY also be able to get other chematics, but I don't know. You can also get venom trap parts, sirens sentry parts and stuff. Check out the crimson citadel page for more info.
