The Corpse Race's full-scale invasion war

It was a combination of Resident Evil and Starship Fleet. This time, the Starship Fleet was no longer facing the Zergs but the higher-level zombies.

The Zergs were like cannon fodder in front of it.

Zombies in front of it were little soldiers,

They were intelligent creatures that were more advanced than the Zergs and zombies, the Corpse Clan.
