GAME-scanner analysis
The cancellation of the Warhammer Horus Heresy MMO is a disappointment for both developers and fans. Jackalyptic Games, a studio under NetEase, had been working hard on the project for the past few years. The studio’s closure after NetEase withdrew funding highlights how fragile game development can be in today’s market. Confirmation from Graham McNeill, a well-known author within the Warhammer franchise, that he had worked on the project shows that significant creative effort went into it. That makes the cancellation even more painful for the community.
What does this mean for players?
For fans of the Warhammer 40,000 franchise, the cancellation of this MMO is a missed chance to experience the iconic Horus Heresy storyline in interactive form. Reactions on social media suggest there is strong demand for a game focused on this important period in the lore. This could encourage developers to revisit the possibility of a Horus Heresy game in future early access development, especially given the rich stories and characters the franchise has to offer.
