All newsPlayers around this dateRead on Steam

Greetings dinosaur hunters!

A new update is released just in time for the holidays! The update introduces aquatic hunting with Mosasaurus now available as a huntable species.
To support this, a new harpoon rifle, a SUP board for water traversal, and improvements to water behavior have been added.

Thanks again for your continued support and happy holidays!

Hunting Mosasaurus


Players are now able to damage Mosasaurus. Please note regular firearms don’t penetrate water. To hunt Mosasaurus we introduce a new type of weapon: harpoon rifle. When Mosasaurus dies its body will surface.
Mosasaurus can be placed on regular, and head stand in the lodge.

New Mosasaurus skin types


Mosasaurus has now full set of seven skins from Common to Erythristic.

Mosasaurus AI update


Mosasaur navigation and diving logic was improved to make hunting it more intense.

New aquatic weapon: Harpoon rifle


From the shop you can find new category Aquatic equipment. In it you’ll find a single shot harpoon rifle. Regular firearms bullets stop on water surface. Harpoons being slower and more heavier will penetrate water making them ideal for hunting aquatic or semi aquatic species. A new ammo type harpoons has been added for this new weapon.

New items: SUP board and paddle


SUP board is another aquatic class item. You need to put it in one of the equipment slots and hit left mouse button to deploy the board. Deploy it on water. You can pick it back to your inventory by looking at the middle section of the board and when you see the tex change to “pick” press E and the board will be back at your inventory.
In order to stand on the board you need to press E when looking at all other parts of the board than the middle. You’ll need to purchase the paddle too if you want to get anywhere comfortably. It’s possible to use the board without the paddle but then you’re able to move very slowly. Paddle is equipped in one of the equipment slots too.
Please note that the board will remain in the place where you left it when you die.

Trophy lodge poses


We have created a system that allows players to change poses on dinosaurs in lodge. Currently these species have different poses that can be applied:

  • Tyrannosaurus Rex
  • Ankylosaurus
  • Carnotaurus
  • Gallimimus


We’ll add more poses to other species later.
