Скачать или смотреть ARK: Survival Evolved - Allosaurus Pack

"Allosaurus always spawn in packs of 3, but packs will merge if they encounter each other. As long as a pack has 3 or more Allosaurs in it, the highest level one will receive a pack boost, which can be identified by a glowing red aura, similar to that of an Alpha Predator. The pack boost applies to both wild and tamed Allosaurs and provides the following benefits:

Increases damage done by 50%
Reduces damage taken by 25%
An extra attack (default Right Mousebutton) that slows the target and does bleeding damage
The ability to roar while mounted on alpha (default C) When the Alpha roars, the others in its pack will also roar.
These buffs only apply to the Allosaurus with the Alpha Boost, however in larger packs, multiple Allosaurus can sometimes become the Alpha." - http://ark.gamepedia.com/Allosaurus
