Beast

Summary
The Beast was a mob that was available during the early development of R2DA. It had only one attack: a swing of its club in the direction of where the mouse went. Despite still being in development, that didn't stop the Beast from being succeeded by the Brute.

Background Story
This was the last common ancestor between the grey, muscular behemoth known as the Tank and the green, club wielding Brute. At this point in the evolutionary ladder, the skin was a soft shade of peach, reminiscent of a person. Although the structure was there, the strength was nowhere near to what the Brute is today. This zombie was extremely rare, and those who saw it usually managed to escape. No-one wanted to face something that was both unknown but still deadly.

As the SANI Virus continued its evolutionary progression, the Beast slowly faded out of existence. There are few survivors still alive that can tell you about this zombie today.
