Additional Notes: Good info, but also could use some more info about actual development history and inclusions, not just current situation. Ill do some more work tmrrw, celebrating new year.
History
Punt began as a modification based on Source 2013. On November 4th, 2016, PUNT transitioned from Source SDK 2013 to a hybrid engine branch based on Alien Swarm[4]. This gave numerous improvements to the shadows, lighting and particle systems. But a month later on December 16th, the project transitioned to the Portal 2 engine branch, which provided greater flexibility for renderer modifications, expanded Workshop support, and additional customization for developer tools, such as the Hammer Editor[5].
Over time, the Portal 2 branch continued getting heavily modified and evolved into "LunchEngine". LunchHouse later extended their engine license to Emberspark Games, allowing LunchEngine to be developed alongside with Portal 2: Desolation's engine branch, "Vitamin". As such, PUNT shares several of features that were originally developed for Desolation, including CSM, Improved Vertex Based Animations, and PBR[6].
Despite being originally planned to release in 2023 and development reaching about 90%, the release has been constantly pushed back due to Valve repeatedly failing to sign the final release agreement required for LunchHouse to ship the game. According to project lead and programmer Caylee's in a statement posted the 15th of August, 2025, "We downed tools a year and a half ago due to contractual issues with our engine provider that prevent our final release - with the engine's owner becoming completely non-responsive to emails at the very final stage of the process,"[2] since these delays kept happening despite the amount of work that was completed, they were forced to pause development. This was very unfortunate, as a sizable portion of development was focused on engine upgrades, particularly the renderer, which had advanced rendering techniques implemented by Caylee & Graham.
The Developers have noted that if Valve does eventually sign the release contract, PUNT will be released under the Source engine as soon as possible, but until then, the current plan is to port the project over to Unity, similar to The Stanley Parable. The reason Unity was chosen was primarily due to Caylee's familiarity with it and its cross-platform support. And while Godot was also considered as an alternative, its console support and issues with .NET C# were deemed too unstable to deal with, so they opted with Unity instead, despite some concerns with its implementation of 
PhysX.
