If you look at that site, time capsules are coming in every few minutes. Unknown Worlds manually approves them, and it's a slow process. But I figure more people upvoting them can't hurt. Plus you get to view some beautiful screenshots and messages. Most time capsules just sit there and get zero upvotes. So be the change you want to see in the world!
According to Unknown Worlds community manager a few months back (pretty sure it was @[email protected]), the following items are banned from time capsules:
- PowerCell
- Battery
- Propulsion Cannon
- Hatching Enzymes
- Enzyme Cure Ball
- ALL Seamoth upgrades
- The following Prawn Suit Upgrades: Depth 1 & 2, Jump Jet, Drill Arm, Grapple Arm, Thermal Reactor
- The following Cyclops Upgrades: Depth 3, Thermal Reactor, Fire Suppression, Shield
- Sea Crown Seed
- ALL of the alien tablets
- Ion PowerCell
- Ion Battery (can be smuggled inside tools but not placed individually)
- Kyanite
Also note that no time capsules showing dead creatures get approved.
(I know all this info is pinned on the Subnautica subreddit, but I figured it's good to have it here too since not all Lemmy users are on Reddit. Sorry if I'm stepping on any toes!)
