Atlas is a new, pirate-themed survival MMO from the creators of ARK: Survival Evolved. While there's some manner of fantasy involved, World War 2-era tanks and airplanes probably aren't part of the planned content. But those are what appeared in Atlas when some player managed to gain access to an Atlas admin account on Steam.
As reported by Rock Paper Shotgun, a hack broke into admin account for Atlas yesterday and took over its North American PvP servers. Though the account was eventually recovered, it wasn't before the hijacker managed to summon World War II-era tanks, planes, and even whales into the pirate survival MMO.
"Earlier today, an admin's Steam account was compromised and used to cause some devastation on our Official NA PvP Network," Grapeshot Games said in a statement. "To be clear this was not caused by a hack, third party program, or exploit. We have taken the appropriate steps to ensure this does not happen again."
While Grapeshot managed to contain the damage by rolling back Atlas to a backup server from five-and-a-half-hours earlier, a couple streamers managed to record the chaos that happened under the hijacked Atlas server. You can see what the randomly spawning tanks, airplanes, and whales look like in the fantasy pirate MMO on Twitch.
Unfortunately as a result of the rollback, some five hours worth of player progress was lost. But that's probably a small price to pay to get your game back into your control and away from a maniacal new overlord. Hopefully this won't cause some copycat to try and one up the airplane, tank, and whale summoner.
