In-Game Difficulty Difficulty Icon

This difficulty aims to make the game tougher in a fair, learnable way. It requires lots of awareness and skill.

It should feel a lot more like the planet doesn't want you here, and is there to obliterate you. You are likely gonna get swarmed.

List of changes:


I have changed lots of enemy AI, mainly to make them less stupid. Some of the more annoying airborne enemies now fight closer up. Some of the less threatening enemies have received major buffs to make them deadly. Bosses have more HP and hopefully feel intimidating now with their skill/AI changes. I haven't gotten around to changing every enemy yet. I also want some feedback on the mod as a whole if possible! :)

Note: Other mods that change enemies might not be compatible with this difficulty.
