Borderlands creator Gearbox Software has announced the codenamed Project 1v1, which blends first-person combat with a card strategy metagame.
They don't go into great detail on exactly how this is achieved but advertise a 'Closed Technical Test' is prepping for later this summer. Those who'd like to take part in Project 1v1 at this early stage can sign up for a beta via the official website.
Three modes will feature in the technical test; Ranked, Challenge and Arena. Crates are earned by defeating opponents and in the ranked mode of the game. This seems to be Gearbox getting into the card game market that's getting increasingly saturated. Recently Valve announced their own spin-off DOTA card strategy.
Project 1v1 is currently listed for PC with a Closed Technical Test this late summer.
