Frequently Asked Questions
What do you need for Water Treatment Plant in Rust?expand_more
You need a green keycard, a blue keycard and a fuse. That's the full requirement to run the Water Treatment Plant puzzle — put the fuse in to power the room, then swipe the cards. Keycards are single-use per swipe, so bring spares if you plan to run it more than once, and don't count on finding one on site.
What cards do you need for Water Treatment Plant?expand_more
Green+Blue card, Fuse. You can craft keycards or find them in monument crates. Green cards are cheap and common, blue cards come from mid-tier monuments, and red cards are the ones worth planning around — our keycards guide covers where each colour comes from and what it costs to make.
Is there a recycler at Water Treatment Plant?expand_more
Yes, Water Treatment Plant 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 Water Treatment Plant?expand_more
Water Treatment Plant has medium 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 Water Treatment Plant?expand_more
Water Treatment Plant is a medium-radiation monument, so a hazmat suit — 50% radiation protection in one slot — is the default answer. A high-resist clothing stack with a lead armor insert or an anti-rad tea also works for shorter runs, but cloth-only players get hurt here.
