Grue

The Grue is a huge Orthrus featured in Resident Evil: Revelations 2's Raid Mode as part of a Huge Creatures online event.

Gameplay
The Grue is a "Huge Creature", that walks slowly towards the player avatars, alongside the Ichor. The damage inflicted on the creature's enormous HP is accumulated through all the online players damage, making defeating them a cooperative effort between all Raid Mode players.
