Hi, I can help complete and polish the Unity multiplayer game using your starter asset, focusing on turning it into a Steam-ready build rather than rebuilding networking from scratch. I’m comfortable working with existing Unity projects, integrating gameplay logic, lobby flow, UI, win/lose states, bug fixing, and preparing clean builds for testing and release. My approach would be to first review the current project and multiplayer asset, confirm the intended game loop, then implement the missing gameplay pieces in a structured way so the project stays maintainable. I can also help with Steam build preparation, basic QA, settings cleanup, and making sure the final package is ready for upload/testing. I understand the confidentiality requirement and can work under NDA, keep the IP private, and follow your preferred repo/workflow. For revenue share, I’d want to align clearly on ownership, expectations, and post-release responsibilities before starting. Question 1: Which multiplayer starter asset are you using, and is it based on Mirror, Photon, Netcode for GameObjects, Fish-Net, or another framework? Question 2: What is the current state of the game: prototype with mechanics already working, or mostly starter asset plus design notes? Regards, Houssame
