How to do Military Tunnels in Rust?

The Military Tunnels are hands down one of the toughest yet most rewarding monuments in Rust. If you’re like me and love high-risk, high-reward gameplay, this is where you want to be. However, don’t go in blind—this place is crawling with well-armed NPCs, high radiation, and a puzzle that can trip you up if you’re not prepared. Let me break down how I tackle it, so you can, too.

Step 1: Gear Up Properly

First things first—if you’re under-geared, don’t bother stepping foot in these tunnels. Here’s my go-to loadout:

• Hazmat Suit or radiation protection (25+ rad resistance) – The tunnels are loaded with radiation, so this is non-negotiable.
• Green, Blue, and Red keycards – You’ll need all three to complete the puzzle and access the best loot.
• Electric Fuse – You’ll need at least one, though bringing two is safer.
• Weapons and Ammo – The NPC scientists in here don’t mess around. I usually pack an assault rifle, preferably an LR-300 or an MP5, with plenty of ammo.
• Healing items – You’ll want a solid amount of medical syringes and bandages to stay in the fight longer.
• Food – I bring pumpkins for that quick heal between firefights.

Step 2: Enter the Tunnels

There are two main entrances to the tunnels. I typically choose the one with fewer players around, which gives me time to handle the first set of NPCs without worrying about ambushes from behind.

You’ll encounter your first wave of scientists almost immediately. I like to engage quickly and with precision—try to headshot them before they swarm. Don’t hesitate to use cover; the tunnels offer plenty of it.

Step 3: The Fuse Room

Once you’ve cleared the initial scientists, you’ll make your way to the Fuse Room. Here, you’ll insert an electric fuse and flip the timer switch. T

his starts the puzzle process and gives you a limited window to swipe your Green Card at the next room, which is located across the tracks in a door marked “Storage.”

You need to be fast here. The puzzle is timed, so once you flip the switch, sprint toward the Green Card room. Every second counts.

Step 4: Solving the Puzzle

After swiping the Green Card, head deeper into the tunnels. You’ll soon come across the Blue Card room, labeled “Laboratory.” Clear out any scientists you encounter along the way, and swipe your Blue Card to proceed. In this area, scientists are well-armed with shotguns, so I typically engage them at range and use grenades if I have them.

Finally, you’ll come across the Red Card Room. Swipe your Red Card, but be ready—the NPCs here are aggressive, and this is where other players are most likely to ambush you, since the best loot is just behind this door.

Step 5: Loot and Exit

Once inside the Red Card Room, you’ll find Elite Crates—these are where the big rewards are. I’ve found high-tier weapons, armor, and other goodies that make the entire run worth it. Just remember: you’re not safe yet.

I’ve lost count of the times I’ve been looted right after I cleared the room. Keep your guard up, and always have an exit plan.

Combat Tips

• Use cover – The tunnels offer lots of places to hide. I move from cover to cover, and always keep my back to a wall when possible.
• Grenades – These are lifesavers, especially when you need to clear a room quickly without exposing yourself.
• Stay mobile – The scientists have good aim. Staying on the move makes it harder for them to land those deadly shots.

The Military Tunnels are a thrill. Whether you’re solo or with a team, the key is preparation and precision. With the right strategy, you’ll walk out with some of the best loot in the game.
