Harmonix's musical first-person shooter, Chroma, has been shared in some early alpha testing, and it looks like the Rock Band publisher has made a decision on the feedback from these tests. It seems more work is needed before Chroma is where Harmonix would like it to be.
Harmonix sent out a letter to testers that says that "Based on the terrific feedback we got from all of you in the community, as well as our own analysis, we have concluded that Chroma will need some substantial retooling to be the game we want it to be."
The letter, published by Kotaku, continues with how they plan to continue to evolve Chroma:
"We remain passionately committed to the high-level vision and we think there are some very successful mechanics and systems in the existing build. The team has, in fact, already started prototyping new directions for the game based on those successful mechanics. We look forward to sharing more with you down the line, as Chroma evolves in new directions."
