Rust Base Building 101: Creating a Simple Airlock ~ HaploGamingChef

Why Every Rust Base Needs an Airlock

If you're just getting started with Rust or coming back after a break, one thing you don't want to overlook is setting up an airlock. It might sound fancy, but in the world of Rust, it's a small build trick that can stop raiders from waltzing into your base when a door is left open. Think of it as your base’s safety net.

When someone opens a door, there's always a chance a stranger could run in right behind them. An airlock prevents that by requiring two doors to be opened in sequence, which makes unauthorized access almost impossible. It's simple to build, doesn’t cost much, and drastically improves your base security.

Getting Started With a Basic Base Layout

Before you even think about airlocks, you need a basic base to attach one to. If you're working solo or just learning the game, starting with a one-by-one or two-by-one base is usually the easiest option. It’s fast to build and gives you enough space to store essentials and craft some gear.

To begin:

Place down a one-by-one square foundation.
Add four walls, a roof, and one door frame.
Upgrade the structure with stone or sheet metal to prevent quick raids.

Once that’s done, you’re ready to think about where your airlock will go.

Where to Place the Airlock

Positioning isn’t everything, but it can help. You’ll want your airlock to connect directly to your main entrance. Whether you place it to the left, right, or straight ahead from your door doesn’t really matter in terms of function — it’s about your building layout and what works for you.

A triangle foundation works best for this setup. It's compact and fits perfectly outside a standard base entrance without blocking paths or structures.

Building the Airlock: Triangle Foundation Method

To create your airlock, start by attaching a triangle foundation outside your main door. This gives you a corner to work with, allowing just enough room for a door and a small buffer zone that makes your base harder to raid.

Here’s a quick step-by-step:

Add the triangle foundation where the airlock will sit.
Place two door frames — one connecting the triangle to the base, the other forming the outer doorway.
Upgrade the foundation and door frames with the same material as your base.

The triangle shape also prevents awkward placements and clipping issues that can occur with square foundations.

How to Place the Doors for Maximum Security

The real trick to making an airlock work isn’t just building it — it’s in how you place the doors. If they open the wrong way, you might create a security risk without even realizing it.

Here’s what you want:

Inner door: should open into the base.
Outer door: should open into the airlock (not outward into the world).

This setup ensures that if both doors are open, no one can slip through. Players need to close one before opening the other. That’s the magic of the airlock — it blocks line of sight and body movement from the outside to the inside.

Locking the Doors the Right Way

Locks matter. Use key locks early on if you're short on scrap, but upgrade to code locks as soon as you can. It’s just faster and lets multiple teammates use the doors without keys.

Each door in your airlock should have its own lock. Don’t skip this. A missing lock on just one door can turn your base into a sitting duck for anyone who stumbles by.

Getting In and Out: How to Use an Airlock Properly

An airlock only works if you use it right. That means:

Always close one door before opening the next.
Don’t leave both doors open, even for a few seconds.
If you're running in from outside and getting chased, prioritize slamming the outer door first — even if you die, your loot stays safe.

Most new players forget this. Practicing the door routine until it becomes muscle memory makes a big difference in surviving long-term.

Common Mistakes to Avoid When Building an Airlock

There are a few traps that trip up new or rusty players:

Doors open the wrong direction: easy fix, just rotate before placing.
No triangle foundation: makes airlocks clunky and easier to door camp.
Using wood upgrades: never do this unless you're desperate.
Forgetting to lock the doors: rookies do this all the time and pay the price.

A little attention to detail during building can save you hours of lost progress if someone manages to sneak in.

When to Upgrade Your Airlock Design

The starter airlock is great for your first base, but once you’ve gathered more resources and expanded, you’ll want to upgrade it. Some good signs it’s time:

You’re storing high-value loot.
You’ve got more than one teammate regularly using the base.
You’ve been raided once already.

At that point, consider moving from a single airlock to double doors, honeycombing, and even trap placements around your airlock area.

How an Airlock Improves Your Base’s Raid Defense

Even a basic airlock can dramatically reduce the chances of someone getting into your base. In Rust, it only takes a moment of distraction or panic to leave a door open. The airlock structure creates a forced pause — no matter how fast someone tries to run in behind you, they’ll be stuck unless both doors are open.

It also helps reduce the chance of getting door-camped. Players can’t just sit outside and wait to rush in. Even if they kill you as you step out, your main loot room stays safe behind the second door.

That kind of protection early on is invaluable, especially on high-pop servers where every moment outside the base feels like a risk.

Scaling Airlocks for Larger Bases

As you move from a basic base to a more developed setup, you can scale your airlock design. One option is to add a second airlock in a hallway or create a series of rooms with multiple locked doors. This forms a kind of layered defense system.

Larger groups might want airlocks at every external access point. For instance:

Side entrances
Roof access
Loot room paths

These aren’t just security measures — they also slow down raiders and buy you time to react or counterattack during online raids.

Using Double Doors vs. Single Doors in Airlocks

Single doors are the easiest and cheapest option when you're starting out. But once you get the hang of things, switching to double doors has benefits:

More room to move through
Smoother access for teammates
Slightly better angles for defending

The principle stays the same: the doors should open opposite directions to maintain the lock. Whether you use single or double doors depends on your space and resources.

Airlocks and Trap Integration

You can also combine traps with your airlock for added defense. For example:

Shotgun traps: place facing the outer door, catching intruders who try to camp your entrance.
Flame traps: a good way to make your airlock uncomfortable for raiders.
Turrets: in advanced bases, automatic turrets near the airlock can stop enemies before they reach your inner door.

This isn’t something you’ll do on day one, but it’s worth considering once you have the resources and blueprint access.

Airlocks in Solo vs. Group Bases

Solo players often stick with minimal airlocks because of space and cost. Group bases, though, can benefit from:

Wider airlocks for two players passing through
More checkpoints inside (secondary airlocks before loot rooms)
Lock sync via code locks for easier group access

In either case, the goal stays the same: keep people out unless they’re supposed to be in.

Making Airlocks Work on Unusual Terrain

If your base is on uneven ground, cliffs, or snow, you might need to adjust your airlock build. Triangle foundations might need elevation tweaks, or you might need to use floor frames instead. The idea is still simple — two doors that force manual opening/closing in sequence.

Try practicing a few different builds in a sandbox server if you’re new. That way, you won’t waste materials when it matters most.

How Airlocks Fit Into a Full Base Design

Airlocks are one piece of the base security puzzle. Alongside them, you should:

Add honeycombing to protect key rooms
Use armored doors once you can afford them
Design chokepoints that slow down intruders
Keep key loot sealed behind multiple doors

A strong airlock gives you control over who enters — and buys time when under attack.

Final Thoughts on Rust Airlocks

There’s no question: if you're building a base in Rust, your first task after placing a door should be building an airlock. It’s simple, low-cost, and easy to set up, but makes a massive difference in your survival rate.

Whether you're playing solo, with a duo, or in a group, this little piece of building logic goes a long way toward keeping your base — and your loot — safe. Make it a habit, and you’ll be far ahead of most new players.

Conclusion

Mastering the basics of Rust starts with smart base building, and adding an airlock is one of the most effective moves you can make early on. It’s not just about blocking enemies — it’s about creating a routine and structure that keeps you safe in moments of panic or surprise. Whether you're building your first one-by-one or expanding into a larger compound, airlocks are always relevant.

By setting up doors correctly, placing your structure in the right spot, and understanding how to use it properly, you turn your base into a much more secure space. Combine it with smart upgrades and you'll be way ahead of the curve in base defense.

Don’t wait until you get raided — add an airlock the moment your first door goes down. It’s quick, cheap, and protects everything inside.
