The game - Barcode World - Dendy | NES

The game is a kind of strategy with a separate mode of fighting between unique units. Units are big and beautiful robots with all sorts of weapons and parameters. The highlight is that you need to create a character for yourself, set its characteristics and give weapons using cards with barcodes scanned by a special device in the cartridge slot. Any leaflet with a standard 13-digit code, for example, from shampoo, will also work.
