Erenshor's Planar March Update Adds Raids To The MMO You Play Alone, And One Man Built All Of It
Raiding in a classic MMO required thirty-nine other people, a scheduled evening, and the grim certainty that at least four of them would not show up. Erenshor has spent its entire existence arguing that you only ever needed the feeling of that, not the logistics. As of this morning, it is making the argument at raid scale.
The Planar March, the largest content update in the game's history, went live on Steam at 10:00 a.m. Eastern today, free to everyone who owns the game. It adds four raid zones, 21 raid bosses, more than 120 new equippable items, a new raid UI, tiered raid progression, and cosmetic transmog slots. Burgee Media estimates 30 to 40 hours of new content for a typical player. The base game is 15 percent off to mark the launch, down from $19.99.
Raiding Without The Raid Guild
For the uninitiated, Erenshor is a single-player game wearing an MMO's clothes. The world is populated by SimPlayers, hand-coded AI adventurers who level up, form parties, join guilds, chase gear, and generally live their own lives in the background, whether you are watching or not. There is no server. There is no internet connection. There is just the texture of a populated online world, simulated.
The Planar March takes that premise to its logical destination. Your raid group is a SimPlayer roster you assemble, and the new raid UI is the tool for commanding it, letting you designate an A Team that auto-fills into any raid you start and issue broad directives rather than micromanaging every ally through every mechanic.
The four raids are the planes of Fernalla, Vitheo, Brax, and Soluna, tuned for max-level characters with reasonable gear and a few Ascension levels behind them. Entry comes through runes scattered across the world that open the planar portals. A fifth and final raid is planned before the game's 1.0 release, currently targeted for 2027.
"Massively Multiplayer" Made By One Man
Burgee Media is one person. Brian, who goes by Burgee, built Erenshor in the hours around a day job until the game sold well enough that he could quit it. The game has moved more than 80,000 copies in Early Access and sits at 94 percent positive on Steam.
That context reframes what shipped today, because a raid encounter in this game is not one piece of work. It is two. Burgee has to design the boss mechanic, and then he has to teach the SimPlayer AI to recognize and correctly respond to that same mechanic, or the fight simply does not function. Every clever idea about a boss doubles into a second problem about the ten simulated allies who have to understand it. He described the process to GamesRadar as "a really cool exercise in duality," which is a generous way to describe building every fight twice. He has also said he wanted raids in the game since launch day but had no idea how to make them work, and spent the interim rewriting old code until they did.
Twenty Minutes At A Time
The design goal is giving players the MMO experience without the social pressures of having to always be online. These raids are built so a player can make meaningful progress in fifteen or twenty minutes, farming class armor drops in the time an actual MMO raid would spend forming up and arguing about loot rules.
That is the whole thesis of Erenshor compressed into a feature. The nostalgia people carry for old-school raiding is rarely nostalgia for the four-hour commitment or the attendance spreadsheet. It is nostalgia for the fight, the coordination, the loot, and the shared sense of a world being played in. The Planar March delivers those without the calendar invite, and it does so because one person spent a year teaching an AI how to hold a threat table.
Erenshor is available now on Steam, currently 15 percent off. The Planar March is a free update for existing owners.
