Creature Threats, Damage, and Wrecks

Navigate the waters carefully, some creatures will violently attack the Cyclops if drawing too much attention. These attacks can cause hull damage and fires. If hull strength reaches zero, the Cyclops will sink to the bottom of the …

Subnautica features submarines. What happens when you drive a submarine into a rock, or a large alien life form gets a little too friendly? Watch this video to find out:

Sylvain has been hard at work creating these effects. This is a technical prototype, and not representative of the quality of the final game.

As the water level rises, there is less and less room to hide, and to breath. Perhaps if a submarine is not repaired fast enough, it will sink – And all the hard work that has gone into customising it, all the equipment stored on board, and even your life could be lost.…

Cave Thing is painted with a diver’s mask at the edges, hinting at Subnautica’s first person nature. On the right, a small vehicle of some kind if shining lights on to the evidently bemused creature. Small vehicles will be pilotable (or this one an un-manned drone, supporting the swimming player?), deploying from ‘mothership’ style larger vessels (See Exterior Sketch for more about this!).

Most importantly, this little encounter is …

One week ago, we revealed that Unknown Worlds is working on a new game: Subnautica. We want to share Subnautica with you from its earliest moments, bringing you concept art, early design thinking, and more.

Today we are following up on the original three concepts with Exterior Sketch. This concept was only the second ever to be created for Subnautica, penned by Cory after he completed Interior Hallway (We’ll show you that one later!)

Exterior Sketch was the first attempt to give form to an idea that is central to Subnautica: That players would interact with substantial underwater vehicles. These submarines would enable exploration and discovery by providing protection, mobility, and utility below the ocean surface.

Since this art …
