The Pachycephalosaurus is a playable creature in beasts of Bermuda. It is a herbivore, requiring only to eat plants around the map to fill its food. It is terrestrial, and does not fare well in deep saltwater.
Its primary attack is fairly standard. It is a small head ram, which inflicts moderate damage. It also applies knockback when it hits with this attack, which is unique to the Pachycephalosaurus. The Pachycephalosaurus is a bruiser, allowing it to inflict significantly more injury damage than others. It also can inflict injury damage regardless of where it hits. This allows its primary attack to inflict injury damage of significant degree, especially to smaller creatures such as the Utahraptor.
Its secondary attack is a charge, which must be initiated while the Pachycephalosaurus is sprinting at full speed. When the secondary attack key (defaults to Right Mouse Button) is held down, the Pachycephalosaurus will begin charging. When charging, it instantly gets a speed boost but has a very poor turn radius. The longer it charges, the faster it goes. Charging rapidly drains ability power, but consumes no additional stamina beyond what would normally be consumed by sprinting. The faster the Pachycephalosaurus is going when it strikes its target, the more damage, injury, and knockback it will apply. A particularly long and fast charge can almost put a Velociraptor into orbit! The Pachycephalosaurus will stop charging if it runs out of ability power or stamina.
