As L1Z1X, win a combat against the Nekro Virus without losing any units.
Lore: Mordai was one of the greatest L1Z1X enhancers. His experiments with cybernetic augmentation went wrong, creating a recursive machine-corruption that turned into the Nekro movement / Nekro Virus. The Mindnet fought a civil war to subdue it, believed it gone for centuries, and then the virus resurfaced.
