Besides CH2, Super Dark Deception CH1 now has some new material as well. Updated material includes a new intro, shard corpses, the flashlight mechanic, and updated Archive Room galleries. Shard corpses are hidden throughout all levels and can be mined to earn extra shards for the Archive Room vending machine! They are not required for S-Ranks.
I feel like enough crazy new stuff is happening in the background that I might be able to do a GE Showcase livestream for Dark Deception this year. Likely after September.
