About The Mod

Aut Caesar Aut Nihil is a total conversion modification for Mount & Blade: Warband, thrusting players into the volatile 1st century AD during the tumultuous reign of Emperor Nero. The mod offers two distinct ways to play. You can embrace the classic Mount & Blade sandbox experience, completely reimagined with meticulously researched Roman legions, new factions, and a wealth of new features. Alternatively, you can embark on an epic, story-driven campaign that will see you rise from the squalor of slavery, navigate a web of deadly political intrigue, and carve a bloody path to the ultimate prize: being crowned Caesar Augustus, ruler of the known world.
