Raid Auctus

Raid Auctus is Cosmic Whale Studio's idle raid-sim, released on Steam on April 1st, 2025 for Windows. The pitch is the MMORPG fantasy with theMMO removed: a roster of twenty classic classes, a wall of raid bosses, and a party that clears content while you answer email. It wears a retro pixel look and a relaxed lo-fi mood, and it is over in an evening, which is either the feature or the flaw depending on why you came.

What the loop feels like

You assemble a squad from the class list, tanks up front, heals behind, and send it at the first boss. The fight resolves, loot converts to gold and crystals, and the blacksmith turns the gold into everyone hitting harder. That's Raid Auctus.

You come back, the roster has out-leveled the early wall, and you are choosing skill nodes for a mage you have never watched fight. A boss that wiped the party yesterday dissolves on contact, so you push deeper, and somewhere past boss forty the credits effectively roll. That's Raid Auctus.

How it actually works

Class and party synergy is the actual game: twenty MMO archetypes, and how efficiently the squad clears depends on composition, so roster-building decisions carry more weight than any single click. Combat itself is passive, with no permanent death or wipe-states to punish an idle roster, while gold and crystals accrue either way. Active participation pays, though: manually joining raid encounters early on accelerates resource income versus pure idling, over a campaign of more than forty distinct bosses.

Progression runs on three named layers. Characters level toward a cap of 200 and spend points in traditional skill trees, ranking nodes up to four times for active and passive effects. The blacksmith converts farmed gold into gear and item power. And Honing, the long-term enhancement system, grants permanent roster-wide stat bonuses that outlive any individual gear piece. A New Game Plus mode arrived after launch for players who want the climb again.

Where it stumbles

The reception on Steam has been mixed, and the complaints are consistent. The whole campaign takes an evening or two to finish, and players who finished it describe the second half as a shallow numbers-go-up march with no tactical choice in it. Post-launch support has been light, with small additions rather than the depth rework the endgame wants. Against sprawling genre mainstays like Trimps, this is a micro-idle: it nails the fantasy of managing a diverse raid roster and then runs out of game to manage it in. Buy it for the weekend it is, not the months you wish it were.

Playing it today

On Steam for Windows, with the community hub hosting the completionist threads and balance debates. No browser or phone version exists. If the party-building is what hooked you, Soda Dungeon 2 runs the same raid-crew idea with more legs, and Guildmaster extends roster management into a full loot economy.

The verdict

A charming, bite-sized raid idler with real class-synergy thought behind it and an endgame that evaporates on contact. The Holy Trinity, minus the scheduling app, minus most of the campaign.
