Hey, check this out, Gimkitters! I was going through the files in Gimkit's new game, Apocalypse, looking for easter eggs, when I found these new devices:
I'm not sure what they do, but they're likely bits of code that modify the Sentry device in GKC to make a moving sentry mechanic. The Zombie Invasion Device may even be some kind of waypoint, which could tell roving sentries where to target. š
They may be released eventually in future Creative updates (or maybe not), but for now, all we can do is speculate what they do...
