Ark: Survival Evolved (stylized as ARK: Survival Evolved) is an action-adventure survival video game developed by Studio Wildcard, Instinct Games,Virtual Basement and Colombian Efecto Studios.

It is scheduled for release in June 2016 for Linux, Microsoft Windows, OS X, PlayStation 4 and Xbox One. The game’s early access began for Windows on June 2, 2015, for OS X and Linux on July 1, 2015, and for Xbox One on December 16, 2015.

In the game, players must survive in a world filled with roaming dinosaurs, natural hazards, and potentially hostile human players.

The game is played from either a third-person or first-person view and its world is navigated on foot or by riding a dinosaur. Players use firearms and improvised weapons to defend against hostile humans and creatures, with the ability to build bases as defense. Players can also customize weapons using items scavenged from the environment. The game has both single-player and multiplayer options, with the latter allowing players to engage in simultaneous gameplay.

Ark: Survival Evolved is off to a hot start on Xbox One.

An unfinished version of the game launched on Micosoft’s console through the Game Preview Program and reached more than 1 million downloads in under a week. Studio Wildcard’s Jesse Rapczak shared the number in a post on Xbox Wire. This is likely a mix of free trials and paid downloads.

Whatever the case, Rapczak said Ark’s fast uptake on Xbox One is a sign that people are looking for big-scale multiplayer survival games on console. He also revealed that the Xbox One version of Ark currently sees more daily players than the PC edition.

“There’s no question that survival games have taken the PC world by storm lately,” he said. “And as the only true large-scale multiplayer survival game available on console, perhaps it comes as no surprise that Ark’s daily Xbox One player count is already bigger than on PC.”

The full, finished version of Ark will be available in June across Xbox One, PC, and PlayStation 4.

Until then, Rapczak said Xbox One players can look forward to new updates to Ark about every two weeks.

“This will eventually include highly demanded features like split-screen support, gamepad customization, UI improvements, tweaks to current game modes, balancing improvements, and all the new content that is going into the PC version,” he explained. “That’s awesome considering there is already three times as much content in the game today compared to the PC launch 7 months ago.”

Finally, Rapczak confirmed that the giant, prehistoric kangaroo creature released for the PC edition of Ark last week will make its way to the Xbox One version in the coming weeks.

A free trial for Ark is available now, while the full game costs $35. This price will go up when the final version launches in June.
