Excella was a scientist and reoccurring minor antagonist in the game, working alongside the main antagonist. She sought the affection of the main antagonist by creating variants of a zombie virus but he made it clear he wasn't interested in her, just her research. After multiple encounters, the player will find Excella withing on the ground begging for help as the main antagonist had infected her with her own virus turning her into a huge tentacle monster.
