Fresh character, no helping it.
Solo.
Leather Only.
No Deaths (Hardcore, delete character + map).
No Map cheating + random map.
No cheating, and no exploiting.
No mods (duh).


Exploiting is would be like, sitting on a rock enemies cant climb or digging a trench all around you base cause the AI can't climb or jump.

Exploiting is Soft-cheating.
