Set on an alien planet in the distant future, gamers hunt their prey in adrenaline-pumping 4v1 matches. Players experience Evolve as a first-person shooter when playing cooperatively as the four hunters, while they control the monster in the third-person perspective, providing a gameplay experience unique to Evolve.

Play as the Monster to use savage abilities and an animalistic sense to kill your human enemies, or choose one of four Hunter classes (Trapper, Support, Assault and Medic) and team up to take down the beast on the planet Shear, where flora and fauna act as an adversary to Hunter and Monster alike. Evolve includes three Monsters, 12 Hunters, 16 maps, and four game modes: Hunt, Nest, Rescue, and Defend.

Turtle Rock Studios and 2K challenge the Evolve community to land 2,000,000 headshots on Monsters while playing as Parnell this weekend between 12:01 AM ET on Friday, May 1 and 12:01 AM ET on Monday, May 4.

If the challenge is met by the community, everyone who plays Evolve during that time will be rewarded with the Parnell Predator Skin, absolutely free! And that’s not all: if the Evolve community blows past the above goal by landing 2,800,000 headshots on Monsters while playing as Parnell, everyone who plays Evolve online during that time will earn the entire Assault Predator Skin Set.

The winning skin will be delivered to players by Thursday, May 7.

Two free maps are also coming to Evolve today on PlayStation 4 and PC. Previously released on Xbox One, the Broken Hill Mine and Broken Hill Foundry maps introduce two totally unique environments: mining caves below the planet’s surface and a fully industrial setting that has you sprinting down factory corridors. Each of these maps also introduces new campaign effects while playing Evolve’s dynamic Evacuation campaign. These maps will be available on all platforms today before 8:00 PM ET.
