Beta registration for Rekoil, developer Plastic Piranha's multiplayer first-person shooter, is now open on the game's official website.

Interested players can sign up for free, though the developers note that registration doesn't guarantee access. Those who've been selected will receive an email and a code to download the game within three days.

"We greatly appreciate any constructive feedback or suggestions you may have for our game," the site reads. "We are inspired by our community and are excited to bring this game to you."
