Promising Metroidvania indie game hits Steam soon, free demo out now

A mix of Hollow Knight style platforming, Axiom Verge combat, Metroidvania exploration, and science, the BioGun Steam release date is set.

The wait for Hollow Knight Silksong doesn’t feel so bad these days, with so many fantastic Metroidvania games springing up to fill the void. Among those I’ve played, my time with the BioGun demo sent it rocketing up my own personal wishlist, so I’m very excited to see developer Dapper Dog Digital set a release date for its upcoming game – and if you can’t wait until then, you can try it for yourself right now with a free Steam demo.

BioGun is a sci-fi Metroidvania game with a fantastic premise. Set with the task of saving your beloved pet dog – and the entire canine race – from a potentially deadly pandemic, you’ve been shrunk down to microscopic size and injected into your pup to aid its immune system in fighting off the virus. The result is a frantic 2D action platform game bringing together Hollow Knight style platforming, twin-stick combat in the vein of Metroid and Axiom Verge, and a delightfully light-hearted spin on exploring the inside of a living creature packed with gorgeous, colorful designs and plenty of exploration.

I really enjoyed my time with the BioGun Clinical Trial demo, being immediately drawn in by its bright, vibrant designs and the distinctive premise (though the ability to name the dog certainly helped too). Your guides are DocX, the white-haired engineer responsible for injecting you into the pup, and Pheobe, an ‘organic smart chip’ that’s tracking the vitals of your faithful hound and is able to alert you to high-priority missions.

As you explore, you’ll meet anthropomorphized versions of the various immune systems – the White Blood Cells, for example, are a group of armored dogs that march through the internals blasting any troublemakers. The early writing is pretty charming, and the concept offers up plenty of potential for all manner of unique enemy designs. You might not want to be eating lunch while you play, however.

The platforming and exploration is fast and precise, with a similar feel to that of Hollow Knight, but the weapon system gives combat more of an Axiom Verge feel. Your basic weapons are always available, but more powerful attacks utilize Atomic Energy, a resource earned by attacking enemies or gathering dropped resources that can also be spent to heal yourself. You’ll also unlock upgrade molecules as you progress, allowing you to augment your own DNA to boost your health, energy, and abilities.
