Borderlands and Battleborn developer Gearbox Software is working on a competitive first-person shooter that “combines the action of fast-paced 1v1 first-person combat with the metagame strategy of a collectible card game,” according to the project’s website. Gearbox is calling the in-development game Project 1v1.

Gearbox said on its website that it’s holding a short, closed technical test for Project 1v1. Players who are interested in taking part can sign up for the beta on Gearbox’s Shift website. Some players have reported that they’re receiving email invites to the technical test from Gearbox.

The Project 1v1 website doesn’t offer much detail on the game beyond naming a trio of modes (ranked, challenge and arena) playable in the technical test. Players will apparently be able to earn crates and new cards by defeating opponents in Project 1v1’s ranked mode. A handful of screenshots of what appear to be environments indicate that Project 1v1 will feature a futuristic sci-fi setting.

We’ve reached out to Gearbox for more details on Project 1v1 and will update with any information the company provides.
