This patch adds a new Difficulty setting to the game (which internally we had under the codename "Submission Mode"). Difficulty level 1 is standard, and it goes all the way up to 10. Higher difficulty levels makes the enemies faster and tougher, as well as making more of them to deal with. Enemy spawners like the Triffids, Egg layers etc will spawn new Virii at a faster rate. You can find this Difficulty setting in the Options window under "Other Options". Play on Difficulty 10 and experience Darwinia on Steroids!
