Evaluation
Mighty No. 9 launched on June 21, 2016. Two DLC packs were released alongside and shortly after launch: the Ray Expansion (June 21, 2016) and the Retro Hero pack (August 24, 2016). Both are fully released, and there are no unreleased DLC entries on the store. The developer has posted no news updates of any kind since launch, and there is no indication of any planned future content. The game shipped as a complete product with a defined set of content, and all of that content has been delivered. No further development activity has been communicated.

About this game

Mighty No. 9 is a Japanese 2D Side-scrolling Action game that takes the best elements from 8 and 16-bit classics that you know and love and transforms them with modern tech, fresh mechanics, and fan input into something fresh and amazing!
You play as Beck, the 9th in a line of powerful robots, and the only one not infected by a mysterious computer virus that has caused mechanized creatures the world over to go berserk. Run, jump, blast, and transform your way through twelve stages using weapons and abilities stolen from your enemies to take down your fellow Mighty Number robots and confront the final evil that threatens the planet!
Every aspect of Mighty No. 9’s development—art, level design, music, programming, etc.—is being handled by veteran Japanese game creators with extensive experience in the genre, all the way up to and including the project’s leader, Keiji Inafune himself!
