Frequently Asked Questions
What do you need for Underwater Labs in Rust?expand_more
It depends on the layout. Underwater Labs is generated fresh for each map, so which keycards and fuses its doors ask for changes from one to the next; there's no single route to learn, so check each door's reader as you reach it.
Is there a recycler at Underwater Labs?expand_more
Yes, Underwater Labs has a recycler on site. That matters more than it sounds — you can break components down into scrap before you leave instead of hauling them home, which cuts what you're carrying if you die on the way back.
Do you need a hazmat suit for Underwater Labs?expand_more
Underwater Labs has low radiation, so bring rad-resistant gear — a hazmat suit covers it comfortably. Radiation protection stacks from individual clothing pieces too, so a full set of decent gear can be enough without a dedicated suit.
How much rad protection do you need for Underwater Labs?expand_more
Underwater Labs has low radiation, so you need some coverage rather than a dedicated suit. A full rad-resistant clothing stack holds low-rad zones, and a hazmat suit's 50% radiation protection trivializes them — you'll only take slow ticks if you stand still in a hot pocket wearing rags.
