Level card “Underground base”
Among our many inspiration sources, there were sequences from the video game Uncharted, like this one, where the hero has to run away from a setting that is completely collapsing. The underground base was inspired by such scene and, if you play this card in Snowflake Operation, the infrastructure will collapse while you’re getting through the terrain to interrogate the German officer who is hiding inside. Tiles will have to be removed at the end of each turn, and all characters still on those tiles will be eliminated!
