Our attempt to warm up the Cold Caverns and make them a hospitable place to live has backfired! We appear to have activated an unknown number of previously deep-frozen organic spores. These are now growing and consuming everything in their path. They're a non-newtonian liquid, so bombs are exceptionally ineffective against them! We need to research new forms of defence immediately!
This research unlocks the first of the CryoPlasm defences, the Lancer.
