Trippy game, although I had to play it twice. Kong wouldn't give me the badge the first time, so I had to go through it again on another browser. But playing it twice was kind of fun.
Another way to get 30 combo achievement: Vault Defense, Level 4, Wave 4. Save a nuke. In that level and wave, there are lots of bunnies and spiders. Wait until they're all on the screen and set off the nuke. Works every time.
@Arus51: Good question. In reality, assuming that the world wasn't in total anarchy, the barter system would return. So, we should be paid in chickens, wool, leather or other tradable goods.
@PaulusArtek. I'm so glad someone has found the inspector in Grayditch. After several restarts, I never have found him. Doesn't matter, though, since there are 7 areas and only 6 inspectors. I found my last inspector in Freeside.
