Black Rain was a tabletop game project initiated by https://www.artstation.com/michal_bernat back in 2015. We were both still studying and tried to create something on the side. He did all of the concepts (and game mechanics) and I offered a bit of help with illustrations for cards and promotion. There was even a kickstarter to fund miniatures https://www.kickstarter.com/projects/1466664258/blackrain-alphastrain
