Abyss2 - Zombies
Design/Production: Nexon
Texture/Modification: Nexon

The rescue team sent to rescue the survivors from B-1 of the Rex Research Center was supposed to take a detour through Building C, the soldier training facility.
However, Building C-5, which provides access to B-1, has already been attacked by unidentified creatures.
The rescue team and the survivors they encountered tried everything they could to get out, but that only awakened the dormant abyssal entity...

Humans: Survive the zombie attack until help arrives. Keep an eye on your teammates because one of them might turn into a zombie. You can kill all zombies.
Zombie: The zombie must kill all humans and turn them into zombies. Zombies have higher health and movement speed than humans.
