The cake screenshot is from Spike's Shaft 25 map. So, yes the map is available as part of the pack download or you can test the map out in LiveView.

i mean the one with the cake but its obious its not available but i just wanted to see around the details is such a pretty place idkk if its a map or smt i would love to explore it around

I am echoing Sedawkgrep and saying that it is great to have another map pack after 25 good years! Huge thanks to all the mappers who help to keep this wonderful game still alive!

Which one?

There will be a showcase video soon. :3
I wish I could have the drive to do more maps and keep working on Deck. But real life got in the way. And I don't have the drive to do maps anymore. :/

Congratulations and big THANK YOU to the team for putting this together and giving to the community after 25 great years. It's wonderful to see that people are still creating new maps! And thanks to Tig for hosting the seemingly last bastion of Quake 3.
Look forward to another anniversary pack!
