About Bio Tank
Bio Tank is a fast top-down arena shooter with a ridiculous setting: your dog is sick, so you drive a tiny tank inside it and shoot the infection from within. It's cute, quick and a little silly.
Destroying infected cells earns experience. When you level up, you pick the next pill your dog swallows, and each pill upgrades the tank in a way that changes how you fight. Those choices are the real heart of the game, since you build the tank as the run goes on.
You play with the keyboard and the mouse. It was made for a game jam, so it's a compact arena shooter and not a long campaign. You can play Bio Tank online with nothing to download, and Bio Tank free costs you nothing at all.
How to Play Bio Tank
- Move with WASD or the arrow keys.
- Left-click to shoot the infected cells.
- Right-click to dash out of trouble.
- Press Space to confuse every enemy on the screen.
- Collect experience from destroyed cells, then choose which pill the dog swallows next.
What to Expect in Bio Tank
The idea is sweet and funny at once. The infection is your enemy and the dog is the world you're fighting in. The art is cheerful, but the shooting underneath is quick, so you'll be dodging and aiming a lot.
Each run changes with the pills you pick. You clear cells, level up and feel the tank change, and the dash and the screen-wide confusion move give you tools when a wave gets crowded. It's an easy game to learn and a fun one to replay, with chiptune and synth music that keeps up with the pace.
Tips for Bio Tank
- Keep moving. Standing still in an arena shooter is how you get swarmed.
- Dash with right-click when you're surrounded rather than trying to shoot your way out.
- Save the Space confusion for the moment the screen fills up.
- Think about your pill choices, since every pill changes how the tank plays.
- Fire in short bursts and aim carefully so you can keep the crowd under control.
