Warhammer 40,000: Boltgun is already out on Switch digitally, but a physical version is coming soon. A listing for the boxed version has started to appear at retailers. We originally saw Warhammer 40,000: Boltgun, a retro-styled first-person shooter, on Switch back in May. You can find some information about it below. Load up your Boltgun and plunge into battle headfirst!...
