Albertosaurus are dinosaurs in Additional Creatures.


Albertosaurus is a medium-sized Tyrannosaur often found in temperate to colder climates. While not as large or powerful as some of its other relatives, Albertosaurus makes up for it with intelligence and adaptability. The creature is quick to capitalize on the significance of past experiences, and come up with new ways to change its fighting style or add to its arsenal, or ways to augment its own body. This ability makes Albertosaurus a worthy mid-tier mount, able to grow new skills for its arsenal, and even adapt its fighting style to what its survivor may need!

Left Click - Bite

35 Base Damage

Right Click - Roar

R - Sit

Automatically dismounts. The Albertosaurus can also generally be told to sit. This slightly increases healing rate and decreases hunger rate.

Upon killing any adult creatures above 250 drag weight, the Albertosaurus gains hunt points. It gains 1 hunt point for creatures between 250 and 500 drag weight, it gains 2 hunt points for creatures above 500 drag weight, and upon killing alphas gains an additional 5 hunt points. These can be spent in the Albertosaurus's inventory on new attacks and abilities. Once the ability is unlocked, it needs to be 'consumed' in order to be used. These attacks and abilities are the following:

450 Hunt Points - Right Click (Togglable with O) - "I Recognized This"

50 Hunt Points - C - Crushing Bite

40 Base Damage - Inflicts a slowness debuff that halves movement speed. The duration of this debuff is by default 10 seconds, but increases or decreases depending on the drag weight of the target, determined by this formula: (250/DragWeight)=Increase/Decrease multiplier to slowness duration.

Example 1: Utahraptor - (250/85)10= Slowness duration is 29 seconds

Exmaple 2: Carnotaurus - (250/250)10 = Slowness duration is 10 seconds

Example 3: Brontosaurus - (250/1000)10 = Slowness duration is 3 seconds

50 Hunt Points - X - Shoulder Bash

45 Base Damage - Knockback - Cannot Be Used While Moving

500 Hunt Points - Thin Hide - -25% Defense, -25% Weight, +50% Speed

500 Hunt Points - Dense Muscles - -50% Defense, +25% Speed, +25% Damage

25 Hunt Points - Swift Swim - Allows for sprinting while swimming.

500 Hunt Points - Thick Hide - -50% Speed, +25% Defense, +25% Weight

With Thin Hide, Dense Muscles, and Thick Hide, only the first one unlocked will ever be used by the Albertosaurus, so make your decision wisely.
