Rust’s post-apocalyptic survival gameplay often requires navigating through various monuments to find high-tier loot. Keycards are essential for unlocking doors at these monuments, and understanding how to acquire and use them is critical for efficient progression. In this guide, we’ll break down how to find every keycard in Rust: Green, Blue, and Red, and how to maximize their usage.

Understanding Keycards

Rust has three types of keycards, each granting access to progressively higher-tier loot rooms:

• Green Keycards: Entry-level, commonly found, and open basic loot rooms.
• Blue Keycards: Mid-tier, unlock better loot rooms but require some preparation.
• Red Keycards: High-tier, provide access to the most lucrative loot.

Where to Find Keycards

Green Keycards

Green Keycards are the easiest to acquire and can often be found at basic monuments. Look for structures like:

• Gas Stations: Inside the office or under a desk.
• Supermarkets: In the office or administrative area.
• Lighthouses: Near the base or inside containers.
• Junkyards: Found in the office building.

Pro Tip: Green keycards are sometimes guarded by low-level scientists or require minimal combat. Always carry a flashlight or torch to spot them in dark areas.

Blue Keycards

Blue Keycards require a Green Keycard and Electric Fuse to access certain areas. Locations to find Blue Keycards include:

• Satellite Dish: Use a Green Keycard to unlock the room and retrieve a Blue Keycard.
• Sewer Branch: Activate the fuse, swipe the Green Keycard, and loot the room for a Blue Keycard.
• Harbor (small and large): Insert a fuse, swipe the Green Keycard, and grab the Blue Keycard inside the designated room.

Pro Tip: Bring tools for repairing or accessing the electricity panels, as some locations require interaction with the fuse box before swiping.

Red Keycards

The most valuable keycards, Reds, require a Blue Keycard and typically more challenging monument exploration. Look for Red Keycards at:

• Airfield: Insert a fuse, swipe the Blue Keycard, and navigate through puzzles to retrieve the Red Keycard.
• Power Plant: Requires multiple fuses and a Blue Keycard to access the loot room.
• Train Yard: This monument is more complex; you’ll need a Blue Keycard, fuse, and careful planning to retrieve the Red Keycard.
• Water Treatment Plant: Similar to other Blue Keycard rooms, requires fuse and puzzle-solving.

Pro Tip: Red Keycard locations are often heavily guarded by scientists or other players. Go prepared with weapons, armor, and medical supplies.

How to Use Keycards

Once you’ve collected keycards, you’ll use them to open corresponding doors at various monuments:

1. Find the Puzzle Room: Most locked rooms have puzzles requiring you to interact with fuses or switches.
2. Swipe the Keycard: Use the appropriate card (Green, Blue, or Red) at the card reader near the locked door.
3. Loot Efficiently: Red rooms have the highest value loot, including weapons, resources, and tech, so be sure to have enough inventory space.

Tips for Keycard Runs

• Prepare for PvP: Monuments are high-traffic zones where other players might ambush you.
• Bring Fuses: Always carry a few Electric Fuses as most puzzles require them.
• Travel Light: Ensure you have enough room to carry the valuable loot found behind keycard-locked doors.
• Scout First: Observe the monument for enemy players or NPC scientists before making a move.
• Team Up: Red Keycard monuments are safer to raid with a team, as they often have stronger enemies.

Conclusion

Keycards are a crucial part of Rust’s progression system, offering access to some of the best loot in the game. By mastering the locations and puzzle mechanics, you can efficiently gather Green, Blue, and Red Keycards to secure a significant advantage. Just remember to stay vigilant, as competition for these resources can be fierce. Happy looting!
