Master Blaster Zero is a cool little game on the Switch, and the developers were cool enough to give owners of the game free DLC.
Actually, they were even cooler than that: you can download the free “Gunvolt” DLC even if you don’t own the game.
The DLC is free to download until May 17th, so if you’re considering buying the game in the future (maybe when it’s on sale), you can grab the DLC right now.
You can find the DLC on the game’s product page on the Switch eShop. Keep in mind that you can only grab it on the Switch console and not on the Nintendo website.
After May 17th, the DLC will cost $2. It adds “Gunvolt” from Azure Striker Gunvolt as a playable character in the game.
