Frequently Asked Questions
What do you need for Water Treatment Plant in Rust?expand_more
You need a fuse, a green keycard and a blue keycard. That's the full requirement to run the Water Treatment Plant puzzle: put the fuse in to power the room, then swipe the cards in order. A card isn't used up by one swipe: each successful swipe wears it by one use, and a wrong card costs nothing (swipes per card here — Green Keycard: 4, Blue Keycard: 4).
What cards do you need for Water Treatment Plant?expand_more
Green+Blue card, Fuse. Keycards can't be crafted: you loot them, and the red one can also be bought at Bandit Camp. Our keycards guide covers where each colour comes from.
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.
