After a few posts mentioning a certain enemy, I came to the conclusion that they will not return unless we have more support. Which enemy you ask? Tortodrones. I remember Nick posting (I forgot which thread) that tortodrones would be back (with some new attacks), but they haven't come back since Nick's post and now.
If we get more people to request the return of T-drones, then maybe the Devs would bring it back.
If you want to have T-drones to return, then please state so in your post. If the Devs see it, they just might make the decision to re-integrate T-drones into normal gameplay. I honestly would be fine if they put it in LD as a surprise to all the players (they'd be like WTF) and have it there, but clockwork T-drones would be preferable. Thank you for taking the time to read this request. Hopefully you support it too!
