The latest Arc Raiders patch is almost entirely about fixing exploits, including all the clipping through locked rooms business

"A fresh Arc Raiders patch has arrived, bringing a host of new fixes to several exploits players have recently been relying on to do things they're not supposed to, and bypass certain mechanics to get into areas without having to go through proper channels. The patch is fairly small, and surprisingly doesn't include any buffs or nerfs to anything in particular."

"This fix applies to all maps, and it's intended to address an issue whereby players would not bring the required keys to access those areas of the various maps. Locked rooms, if they can be unlocked, often hide a wealth of high-tier and rare loot. But players have also been using similar exploits to clip through walls and access areas outside the playspace, allowing them to ambush enemy players and set up traps that would be impossible for others to detect."

Update 1.4.0 focuses on closing several exploits allowing players to bypass intended access and enter off-limits areas. Exploit mitigation mechanisms were added for all locked rooms across every map to stop players from glitching through locked doors and accessing high-tier loot without required keys. Fixes prevent clipping through walls and exiting the playspace, which previously enabled undetectable ambushes and trap setups. Exterior access to the locked room inside Spaceport's Control Tower was blocked so the room is only reachable from inside the tower. The patch also resolves a quick-weapon swap exploit and includes various smaller lighting and texture bug fixes.
