Several tiles in the map are exposed to the vacuum of deep space due to extensive damage to the Corpus Ship, which will slowly drain shields, and then health over time. Unlike with Corpus Ship decompressions, there is no way to seal the rooms, and thus players must take care not to spend too much time on tiles suffering decompression. Also, in rare cases the decompression effect may carry over into the next room even if said room normally doesn't have the condition. This tileset is notable for having the only Insertion and Extraction tiles exposed to atmospheric decompression.
