BioGun

I have a soft spot for the small studios that build something genuinely strange and then pour every ounce of craft they have into it. BioGun is exactly that: a side-scrolling twin-stick shooter metroidvania from Dapper Dog Digital where you play as Bek, a vaccine synthesized from pig DNA, fired into the body of a dog to fight off a catastrophic viral outbreak called the Dooper Virus. The premise sounds like a pitch that should have been rejected in a pitch meeting. It works. What keeps it working is the hand-drawn art, and I want to be specific about that because screenshots do not fully capture the quality here. Every enemy, every cell you befriend, every pulsating corridor wall is traditionally animated frame by frame. The result is something alive in a way that vector-drawn indie art rarely manages. Each organ region carries a distinct color palette so you always know where you are, and the world shifts from bright bubbly gastric chambers to darker, more ominous necrotic passages with enough visual contrast to stay interesting across the whole run. The soundtrack, composed by Juhani Junkala, earns its place too. It sits low enough not to crowd the action but does something quietly essential: it keeps the biological, slightly surreal atmosphere pressurized without ever tipping into parody. The gameplay loop combines metroidvania structure with 360-degree twin-stick shooting, and the two actually complement each other better than you might expect. Bek starts with a dash and a basic blaster, then accumulates weapons and abilities through quest rewards and exploration. The Cyto Blaster handles single-target boss damage reliably; the Proton Smasher clears groups. A Nano-Chip system lets you slot passive modifiers at save points, nudging your playstyle without adding complexity you didn't ask for. The map is unusually readable for the genre, and beating bosses can unlock shortcuts and clear hazardous environmental zones, so the game actively reduces friction as you push deeper. Save points are a little sparse in places, and some players who lean heavily on the keyboard-and-mouse setup will find the Bumper Jumper controller scheme is the correct default for a game built around dual-stick aiming. Worth knowing before you start. The engine under the hood is Construct 3, a browser-game framework, which introduces occasional frame-rate sensitivity when browser tabs are running alongside the game. It is a small and easily solvable annoyance but it is there. Where BioGun is messiest is tone. The world builds genuine atmosphere in its quieter moments, only to puncture it with a brand of silly humor that does not always read the room. One checkpoint sequence involves Bek stripping and performing for the camera. Moments like that are not frequent enough to ruin anything, but they do interrupt an atmosphere that deserves more protection. The writing is quirky, the optional boss fights add satisfying challenge, and the late-game platforming sections with a full upgrade kit are the kind of thing that makes you sit up straighter. Some players will also find the combat difficulty spiky without a formal difficulty selector, though the full 1.0 release landed with 87 percent positive Steam ratings, suggesting most of the rough edges from early access were addressed before the July 2024 launch. For a single-person or micro-studio debut, BioGun is a quiet triumph in the things that matter most to me: intentionality of setting, the texture of its hand-crafted art, and a soundscape that understands its own game. It is not the most mechanically complex metroidvania on Steam, and it does not need to be. It knows what it wants to be and it mostly gets there. Kai, Scout Team
