After demolishing my windmill, I cannot build something in its place nor can i do anything else with the spot. The picture of the windmill stays in that spot.
Nevermind figured out the how the parts work. After you complete the initial 4 artifact parts you can continue to collect them for research which costs one part and $100,000. The research adds a 5% from one of the random upgrades. Parts can be collected from the dark maps at 3, 6, 12, and 14 (from what i've seen).
That was very anti-climactic. A decent game but i didn't feel very accomplished at the end, and the coin thing... I thought developers would learn from mistakes like these. 3/5
easiest way to farm so far is to get 2 elite rhinos, then go to the first boss and destroy the building. with enough skeletons, they will constantly push your rhinos back but with the zombies constantly spawning you can just watch them take out a bunch. though you need to meteor and heal your rhinos(if your aura heal isnt high enough) occasionally.
