π Subsurface Update 0.3 β Into the Deep

Update 0.3 is here!
This update brings major multiplayer improvements, new monster behaviors, a fully playable roulette table, new diver suits, new achievements, improved loot physics, and plenty of fixes and polish throughout Subsurface .
π Multiplayer Improvements
Multiplayer has received several improvements to make other divers look and behave more naturally.
Improved player movement synchronization across the network. Other players can now see your diver looking up and down . A diver's upper body now naturally follows their vertical view direction. Improved how player movement and positioning appear to other players. Fixed major multiplayer issues that could cause players to fall through maps or become incorrectly positioned after entering a dive. Improved player synchronization when transitioning between the submarine and dive locations.
π° Roulette
Feeling lucky? A fully physical roulette table has been added to the submarine.
Bring back your scrap and risk it for a chance at a much bigger payday.
Physically place your scrap in the roulette betting area. Bet everything on Red, Black, or Green . π΄ Red β 2x β« Black β 4x π’ Green β 10x Winning increases the actual value of the scrap you wagered . Losing destroys everything you put on the table. The roulette wheel and ball are fully physical. Sold scrap now physically piles up in the selling area instead of simply disappearing.
Just remember: that $300 piece of scrap is only worth $300 until you decide Green looks tempting. π
πΉ Monster Improvements
Several creatures have received new or improved behaviors, making encounters more distinct and unpredictable.
The Eel can now interfere with your flashlight when it's nearby. The Listener now hunts based on the noise you make. Crouching is much quieter, while sprinting can attract it from significantly farther away. The Skitter freezes while being watched but rushes players when nobody is looking. The Collector can now steal the most valuable piece of scrap you're carrying when it attacks. DoorBlocker now properly defends its territory, charges nearby players, and returns to its position instead of endlessly chasing. General monster movement and behavior improvements.
Pay attention to what you're dealing with. Running isn't always the answer anymore.
π€Ώ New Diver Suits
Two new suit colors have been added to diver customization:
π₯ Gold π Rainbow
More ways to look fashionable immediately before being dragged into the darkness.
π New Achievements
Three new achievements have been added for the roulette table:
Beginner's Luck β Win a roulette gamble. Against the Odds β Win a roulette gamble by betting on Green. All or Nothing β Wager at least $1,000 worth of scrap in a single roulette spin and win.
Good luck with that last one. π°
π¦ Gameplay & Polish
Flashlights now properly follow the player's view. Flashlights can be toggled on and off while carried. Improved dropped-loot physics. Improved positioning when dropping items. Loot is less likely to spawn through walls or underneath floors. Individual scrap values are now preserved when items are picked up and dropped. Roulette winnings therefore remain attached to the physical piece of scrap. Improved settings behavior when transitioning between scenes. Added more physical feedback and environmental detail to the submarine's selling area.
π οΈ Bug Fixes
Fixed major multiplayer player-positioning issues between scenes. Fixed issues that could cause players to fall through dive maps. Fixed several stamina-related issues. Fixed an issue that could result in unlimited stamina after ending a dive. Fixed settings buttons becoming unusable after transitioning between scenes. Improved monster navigation and movement behavior. Various multiplayer, physics, UI, and gameplay fixes.
π Thank You
Thank you to everyone playing Subsurface , reporting bugs, giving feedback, and supporting the game during Early Access.
Update 0.3 is one of the biggest updates to Subsurface yet, and there's plenty more to come.
Good luck down there, divers. π
