Harmonix launched a crowdfunding campaign to bring Rock Band 4 to PC, but it has a significant hurdle to overcome. The rhythm game campaign has just 24 hours left to reach its goal, but it still needs more than $750,000 to succeed. If it doesn’t reach its goal, it may never come to PC.

The Fig campaign is looking for $1,500,000 and intends to bring Rock Band 4 and Rock Band Network to the PC. Rock Band Network allowed players to put their own songs into Rock Band 3, but it was closed down in 2014 due to the amount of work that had to be put in to keep it running. However, if Rock Band 4 does, in fact, come to Steam, developer Harmonix says it’ll be a lot easier to implement via Steam Workshop.

The raised money, if successful, would be used to pay Sumo Digital to port the game to PC. The full cost of development would be $2,000,000, and Harmonix said it would provide the other $500,000 if it reached its goal.

About halfway through the campaign, Harmonix added a new reward tier that would give people the entire DLC song library if they paid $2,500.

Harmonix participated in a Reddit AMA, in which the developer said that the PC would not be “dead to [it]” if Rock Band 4 isn’t funded.

“It’s more about whether or not it makes sense to bring a future game to the platform,” the developer said. “Rock Band VR is coming to Oculus, which is obviously PC, and I can definitely see other titles fitting nicely on PC as well.”

Rock Band 4 released last year on PS4 and Xbox One. It was scored a 7 in GameSpot’s review, which said “[a] lack of content and general stagnation hold this particular iteration of Rock Band back, but new ideas like Freestyle Solos genuinely enhance the core experience.”

Harmonix isn’t new to crowdfunding. The developer sought funding for another rhythm game, Amplitude, back in 2014. It was a successful campaign, raising over $800,000.
