I've been coding on Moosy the whole day again, and I've finally reached a stage where 5angel can start making levels. He also came up with an overall map and some concept art that he and I would like to share with you. You can click on the images to get a slightly higher resolution.
Here you see from left to right: The Strawberry Zombie Alien, a hanged civilian in the Ruby Woods, an alien and the Alien Castle.
On a side note, a new patch for S.T.A.L.K.E.R. is out, so maybe I'll try to play this game once again.
