The header is a from a custom map that's slowlllly coming together. WheatleyMF's 'Savage' map is set in a desert canyon, steep walls hemming in the action like no other Rust map you've ever seen. It'll be an interesting place to explore when it's finally completed. There's a downloadable preview available in the Rust Cartographers Discord, but it's very unfinished so I'm not directly linking to it.
When it's finished, months from now, it'll have its own custom lore. I look forward to exploring it.
WheatleyMF isn't the only one working on a map with its own lore. Meza's Expedition map is an island-based map built to help solos and small groups, but it's dotted with scenes from other games and has its own mysteries.
If you want to test it out, open the F1 console and join with connect 126.96.36.199:28016. You can also poke around a more surreal world made by jeseipi. Their Quadrants map is not a normal place: a world of square islands and giant crystals. It's not something you'd want to play for a full cycle, but it's an intersting place to explore.
Finally, Drakess State has another map.
Reddit seems to have been trying its best to bring bits of the game into the real world this week. Mostly via AddSomeMemes, who showed off his prop-making skills with some cosplay, a pipey, and even a military crate.
Others got involved, too. TheCJ_121 made a lock, and ketchup made an eoka.
And finally, though I'm not even sure if this counts, but we had a marriage proposal thanks to Rust...
