Left 4 Dead developer Turtle Rock Studios today announced that upcoming multiplayer shooter Evolve will be released globally on October 21 for Xbox One, PlayStation 4, and PC.

Those who pre-order the game from participating retailers will receive the Monster Expansion Pack, which includes the Savage Goliath skin at launch, as well as a new monster character when it becomes available after Evolve is released.

Some selected retailers will also offer the Exterminator Weapon Skin Pack or the Instant Hunter Pack.

Evolve blends cooperative and competitive multiplayer experiences as a team of four hunters face off against a single, player-controlled monster. Set on an alien planet in the distant future, players hunt their prey in 4v1 matches across multiple game modes and more than a dozen maps.

“It’s kind of like a big, epic boss battle, but the boss is controlled by a human,” said Turtle Rock Studios co-founder Phil Robb.

Those hunting the monster have the choice of four classes – Assault, Trapper, Medic, and Support.

Turtle Rock previously revealed playable characters Markov, Griffin, Val, and Hank, and have now unveiled Hyde, Maggie, Lazarus, and Bucket.

According to the studio, Hyde (Assault class) carries a mini-gun capable of turning forests into tossed salads, but it’s his secondary weapon that does the most damage; a flamethrower built into his left arm. He also has a unique weapon in Toxic Grenades, as well as a personal shield.

Maggie (Trapper class) totes a machine pistol and harpoon traps, but can also deploy Mobile Arenas – cage-like domes that temporarily enclosing the target in a small space. She also has a companion pet called Daisy, a “big aggressive hyena” who can sniff out the target and revive teammates.

Lazarus (medic) is a sniper-rifle-equipped healer whose Lazarus Device literally allows the dead to rise. It’s more effective than his class counterpart’s Medgun, and he also has the ability to cloak.

Finally, Bucket is the only nonhuman hunter to be revealed so far. A bot armed with a guided missile launcher and sentry guns, he also has a silent UAV ability – he can remove his head and control it like a drone to find and track the target.

We’re expecting to see more of Evolve at next month’s E3 convention, which runs from June 10-12 in Los Angeles.
