The “Toxic Swamps” event in Arc Raiders has been dazzling players for several weeks, hinting at the arrival of Hidetaka Miyazaki-inspired toxic zones. Data leaks and datamining suggested that the swamps, and possibly volcanic elements, would appear following the winter event “Cold Rush.” However, that event has already concluded, and the swamps have yet to appear. This article summarizes all the currently known information about the upcoming event.
All known details about the Toxic Swamps event

Below are all the official and leaked details about the Toxic Swamps event in Arc Raiders.
- The event wasn’t officially announced by the developers. However, the data-mining community has uncovered information confirming plans to add such a location or map modifier. For example, a Reddit user named InquistorOverhauls reported this.
- The exact release date is unknown, but the event is expected soon. According to leaks, Toxic Swamps was supposed to launch on January 19th, immediately after the end of Cold Rush. However, the challenges for that week were changed, and there is currently no evidence to indicate a new release date.
- Thermal Rocks will play a key role. Test data mentions the delivery of Thermal Rocks, hinting at the presence of geysers or volcanic terrain. Players expected toxic environments, but thermal elements also suggest the dangers of high temperatures.
The idea of toxic swamps seems daunting, as this world element likely won’t affect hostile Ark robots, but will damage the player, further tilting the game balance in favor of the machines. Perhaps this will make such maps more PvE-focused? We’ll update this page as soon as we know more.
