Powerlevel but as someone who does game dev, a year out is a very, very generous projection based on the current state of the game. Any indie dev knows making a game is a monumental task, let alone a multiplayer shooter. Jet is also clearly being scammed. I don't know if he is paying a real team of 6 indie developers or if he just has 6 indians from fiverr working on this project, but in a year of development time the game should be in a much better state. Inventory systems are difficult, but otherwise only having a few building assets with broken lighting and two weapons with unfinished and broken animations (revolver is unfinished, lever action gun you can clearly see the shoulder during the charge animation) and a terrain system is not what you'd expect from 6 developers working full or part time for a year, even if it's fiverr indians.
Quite possible though that he hired some real devs and felt too good to use a pre-existing engine and had them create their own. That would make the state of the build Jet was messing around in make more sense, but the game is at least 3-4 years out assuming the same pace of development. I really wonder what Jet was thinking with this one, did he just see Sam's life mission of making a video game and decide that was his mission too now? Very odd. One thing is for certain, Jet has finally come across something that will 100% bring him to his knees. Game development is incredibly difficult, time consuming, and expensive depending on the project, and making low poly Hunt: Showdown is no small feat. I would be shocked if isn't eventually cancelled.
