Gearbox is back with another shooter that will mess with formulas and add unconventional hybrid mechanics to the mix. No, this is not another RPG shooter like Borderlands 3 nor is this another MOBA shooter like Battleborn or Overwatch. This is a brand new game that looks to combine shooters with a collectible card game.
The game sounds a lot like the recently revitalized shooter Phantom Dust on the Xbox and Xbox One, another game which used deck building and shooter mechanics.
Project 1v1 is the code name for Gearbox’s top-secret, in-development, competitive first-person shooter that combines the action of fast-paced 1v1 first-person combat with the metagame strategy of a collectible card game
