You vs. monsters

B.I.O.T.A. is an intense 2D action-platformer, in which you command a team of mercenaries and investigate a mining colony infected by an alien plague. Explore a pixel art world packed with mutant monsters and deadly traps. Try to survive using a multitude of guns and various crafts, including a mech, a sub, and a starship.

The best of both worlds

B.I.O.T.A. mixes the charm of retro games (including two-pixel breathing animations) with the modern-day convenience of full controller support, quick saves, customizing the visuals at any time, and a soundtrack so chippy that you'll want to record a cassette mixtape and listen to it on your Walkman.

B.I.O.T.A. is an 8-bit 2D Action Platformer with metroidvania elements about a squad called GEMINI II and their trip to Front Horizon where they need to find the source of corruption. The game offers an interconnected world with different biomes each with their secrets, upgrades and platforming sections to overcome. There are shops in the game where you can buy ammo upgrades, Max HP increase and many more. There are over 40 different color palettes to choose from and can switch anytime from the pause screen. Each adding their unique and distinctive colors and you pick whatever goes your way and what makes the game more fun to you.

The OST and music were a bit nostalgic to the old 8-bit era and childhood days, really fun to listen to while pushing your way through the game.

Short-ish but quite fun platformer shooter with a few gimmick sections, most of which are great, one rather annoying one. Visuals work very nicely, good amount of color options once you unlock them though I do wish there was a dropdown menu instead of having to scroll through every one of them to find the new ones you unlock. Music is EXCELLENT and a definite highlight of the game. I'd give it a good 8/10 and a recommendation for fans of 8-bit style action games.

It's a cheap and fun little metroidvania. Would be cool if achievements were more doable and content based though.
