[PR] Gravity and Gravity Tethers - github_bot - 01-14-2026
PULL REQUEST DETAILS
[feature][station systems][experimental]
About the PR
Gravity is now variable, ranging from 0 to infinity. Gravity Tethers can be used to provide gravity to one or more areas, and stations have a station-wide tether to do so. Local-area tethers and G-force scanners can be printed from the Engineering fabricator. Note: Tethers cannot remove gravity, only increase it.
To move around without drifting in low/zero-G, you'll want to make sure you have **traction** against the ground, or **grip** against a nearby large object, like walls, tables, or manufacturers.
Gravity will affect many things in ways you'd expect:
* Throwing/kinetic projectile distance
* Low gravity brings nausea and disorients you slightly unless you wear space gear. At zero gravity, you drift away.
* Higher gravity slows you down and yanks stuff out of your hands. At extreme gravity, you'll start taking direct injury.
Why's this needed?
More station systems to disable that drastically affect the round without being insurmountable to overcome. (i.e. the entire station shouldn't immediately want to call the shuttle when this is broken)

(*)Station-wide Gravity Tethers provide gravity to space stations/ships. More details in minor notes.
(*)(TESTMERGE) Post gameplay feedback in <a target="_blank" href="https://forum.ss13.co/showthread.php?tid=24832">the thread here</a>: https://forum.ss13.co/showthread.php?tid=24832
(+)Low and zero gravity causes nausea and disorientation unless you wear space gear.
(+)High and extreme gravity causes sluggishness and injury.
(+)Local-Area Gravity Tethers and Gravity Scanners can be printed in Engineering fabricators.
(+)Station-wide Gravity Tethers can be printed by a disk in the CE locker, or from Cargo.
(+)A-zones always have gravity. Some debris/asteroid field areas have localized gravity tethers.PULL REQUEST DETAILS

Very cool. I enjoy things like this existing so we have more of a realistic SPACE simulator. I would also kill for decompression stuff and proper pressurising airlocks but that's for later

Im hoping the gravity tethers get mech/packet access sometime. also I do belive that the tethers should be able to be used by the AI as they are supplied by the APC and the local ones give gravity to the APC

AIs can use the tether if in physical range

I get stuck in corners of rock floors while mining occasionally even when wearing magboots and have to throw a rock in order to gain traction again. It only happens sometimes though... Let me know if examples would be helpful
It also appears that Oshan cargo doesn't work anymore? Not sure if that's due to this change

Best thing to do is file bug reports in the top-right corner when these things happen, whatever info you can provide can help track it down even if it's not a full reproduction.

when the grav gen changes strength the ticking sounds sound like the admin door knock and its scary ;~:
