Blockchain gaming company Gunzilla Games has launched its battle royale video game 'Off the Grid' on Sony's PlayStation 5 and the Epic Game Store. The game features AAA-level graphics and gameplay and allows players to trade in-game assets using Gunzilla's GUNZ blockchain. Gunzilla aims to create player-driven economies by providing players full ownership of in-game assets as tradeable NFTs. The integration of GUNZ into NFT marketplace OpenSea will enable trading of in-game NFT items. Gunzilla raised $30 million in a funding round earlier this year.
