September is shaping up to be a demanding month for players’ time and wallets, and ProbablyMonsters is adding another action RPG to the release rush. Crimson Moon arrives on September 1 for $20, offering replayable missions, precision-focused combat, and solo or two-player cooperative play across a gothic city under siege.
A run-based take on Soulslike combat
Crimson Moon follows a half-human, half-angel protagonist fighting through Gildenarch, a city divided into three districts. The game draws on familiar Soulslike ideas, including deliberate combat and character progression, but places them inside a structure built around repeatable missions rather than a single uninterrupted campaign.
Players can tackle the missions alone or bring one cooperative partner. Difficulty scales according to the party, so the three districts are intended to remain demanding regardless of whether the player is working solo or with a teammate. Completing all three districts consecutively leads to a world boss encounter, creating a larger test after the individual missions. There are three world bosses in total, followed by an especially challenging final boss.
A low entry price in a packed month
ProbablyMonsters is positioning Crimson Moon as an accessible action-adventure RPG, and its $20 standard price is central to that strategy. The game still emphasizes accuracy and mastery, but the lower cost gives players a comparatively inexpensive way to sample its combat and run-based format.
The Deluxe Edition costs $30 and includes the Ceremonial Armor Set, the Axe of the Gods weapon cosmetic, and an expansion planned for release after launch. The source does not provide a date for that expansion, so its post-launch arrival remains the only confirmed timing.
Platforms and release-day competition
Crimson Moon launches on PlayStation 5, Xbox Series X/S, and PC. Its September 1 release gives it an early position on the calendar, but the game will compete for attention with several major releases. The Blood of Dawnwalker, another highly anticipated action RPG, is scheduled to arrive two days later.
The project previously drew positive interest from the source outlet during Game Developers Conference 2026. ProbablyMonsters is also highlighting its gothic-inspired art direction, cooperative support, and epic metal soundtrack as elements intended to distinguish the game from other action RPGs.

Expert View
Crimson Moon’s clearest market advantage is its combination of a low base price and a repeatable format that supports both solo players and small-group co-op. That positioning could help it stand out during a crowded September, especially among players curious about Soulslike combat but unwilling to commit to a full-priced release. The challenge will be converting that initial value proposition into a durable community around its missions, bosses, and cooperative progression.
