After a long wait, the first demo for the mod "Portal: Alternate" has been released. I am happy to finally get it done, but it's not the end. At least, it could not be the end. If there is enough support for the mod, i will happily continue it. I just want to make sure there's interest in it, y'know? Anyways, here is the link to the demo: Portal: Alternate First Map Demo file - Mod DB
And here are a select few screenshots! More are of course available on the demo page.
Thank you for reading to the end, and if you would please spend a few minutes trying it out and giving feedback it would mean a lot! :)
