Arc Raiders developer Embark Studios recently introduced a mysterious map modifier to the extraction shooter, and, also as of recently, players are going bonkers. "Good luck out there Raiders," one detective writes in the de facto Hidden Bunker megathread in the r/ArcRaiders subreddit, where nearly 350 comments as of writing don't know what the hell, exactly, is going on. Located in the dilapidated Spaceport, the Hidden Bunker contains a trove XP in the form of various data terminal once you manage to crack it open – but the hard part doesn't start until much after that. Some players, like those in the megathread, believe the Hidden Bunker data downloads indicate some kind of cryptic, Mount Chiliad-level conspiracy. They just don't know what kind of puzzle it is, or why it's a puzzle, or if it's a puzzle, or… any of it, really. GTA 5 sleuths finally work out the infamous Mount Chiliad mystery after 12 years in the most anticlimatic way possible, right before GTA 6 likely gives them another mystery to solve Behind the scenes GTA 5 camera work reveals Rockstar's trickery, featuring transforming NPCs, random T-poses, and a half-built plane How to solve the Mediterranean map mural puzzle in the Indy DLC "I am too stupid to understand this probably," says one reply to the thread, wondering if the download terminals' red and green lights mean anything in terms of a pattern. "Doesn't understand it.""i found a non-corporeal wall on accident and fell out of the map," says another comment. More positively, "this lets me see the entire bunker from the outside. here is what that looks like." The bunker, essentially a rectangular room with several circular offshoots connected to a larger round room, was also illustrated on a whiteboard one player carefully designed with map keys and arrows. "Anyway," they write about their map, "excited to figure out what's going on with this bunker." You and the rest of us, buddy. Arc Raiders climbs to new Steam peak of over 460,000 concurrent players, beating Helldivers 2's all-time record as the new extraction shooter from ex-Battlefield devs continues growing.
