Arc Raiders developer Embark Studios released update 1.4.0 this week, and in the patch notes teased a “very hot fix for the locked room exploits.” It turns out they weren’t kidding.

Following the release of the patch, players — as they often do — jumped into the hugely successful extraction shooter to give this fix a proper test. They’ve been able to cheat their way into locked rooms as before, but what they now find inside… well, Embark called it a “very hot fix” for a reason.

As redditor Forward_Problem_7550 discovered, locked rooms now turn you into a fireball if you glitch inside. The clip below shows the trap in action.

Reaction to the change is positive, with most players getting a kick out of what Embark has done here. “Best part of this is the clowns doing the glitch lose all their stuff to someone who legitimately opens the door with a key. CLASSIC!” enthused A_Tortured_Crab. “It's genuinely a really good fix,” added vedomedo. “Hopefully this is the mindset they keep going forward. Punish the exploiters and reward legit players.”

Now, some players are saying they’re more inclined to use their keys to enter locked rooms legitimately in the hope of finding “some dingus who hasn't read the patch notes.”

Technically this isn’t a fix, as players can still use the exploit to enter locked rooms. But it is an eye-catching workaround, and will surely put off players from trying to cheat their way inside a room after they’ve been cooked once.

“Would’ve been better if they just didn’t say anything and rolled this out,” suggested Maverixk_. “Imagine all the door glitches finding this out and losing all of their s**t before word of mouth spread. Would’ve been hilarious.”

That’s not all the update did. It’s also patched the gun quick swap exploit. Full patch notes are below.
