Demon Acro
The Demon Acro was a strong Acrocanthosaurus AI that patrolled the temples of a select few older maps. It was a powerful "boss" of sorts, able to face the strongest of player-controlled creatures with little issue.
Due to the removal of AI until the code can be refined and fixed, the Demon Acro no longer exists on any map. This may change in the future, but no information currently exists related to the fate of the Demon Acro.
