GREAT NEWS for all Metroidvania fans:
We’re excited to share that BioGun is now part of a bundle with Haiku: The Robot, another fantastic Metroidvania created by Mr. Morris Games.
Two worlds, two apocalypses: one with cells and slime 🧬 and the other with robots and rust 🤖 — experience both in the BioGun x Haiku: The Robot bundle!
