• Adds a new mutation called "Unstable lagomorph genome", which causes the player to receive two to three random rabbit mutations per day, both positive and negative.
• Adds a new scenario in which the player starts in a custom room in the top level of an XEDRA lab, with the "Unstable lagomorph genome" mutation.

This is a challenging scenario- initially due to the difficulty of escaping the lab and later due to inescapable mutations that reduce carry weight and make it difficult to wear heavy armor. If the player can survive long enough, however, they will eventually gain access to the post-threshold rabbit mutations, which can be fairly powerful.
