Also is Team17 hurting for cash? They were in the last Android bundle as well and the Breed Trilogy is a Halloween sale on Steam.
If that's the case they should just make an actual Armageddon successor instead of all these four worm-limited games with crappy physics.
Checking their Wikipedia I was really surprised by the way that they employ ~75 people, seems a lot considering the quality and presumably budget of their recent output.
