With the latest updates to the PvP survival game Rust, developer Facepunch Studios has brought colored key cards into the game. Especially newcomers to the game often wonder what these cards are for. In this Rust Guide we will show you what you can do with the cards and where you can find them on the map.
Purpose & locations of the colored key cards in Rust
In the course of the latest updates to the survival game Rust, an electronics system has been implemented into the game. This allows you to build your own electronics and power supply for them. In addition, the developer has added three different key cards and door puzzles to the game. You can find the cards in the colors green, blue and red. With the respective card you can open the corresponding doors and stock up on loot.
In the room behind the green door you will find beginner loot, at the blue door you will find mediocre loot and at the red door you will find good loot. Now let’s move on to the location of the key cards. You can find the green card in monuments without having to solve a puzzle for it.
To get a blue card, you have to enter the room with the green cards, where you can often find one. Now let’s move on to the key card with the best loot. You can find the red cards in the rooms that you opened with the blue card. In rare cases, opponents, the Scientists, also drop a green card.
Note: When searching for the colored key cards in Rust, you must always carry one or more fuses with you. To be able to open the locked rooms, you need to plug them into a fuse box to put it into operation.
