In this concluding update, expansions will be introduced to enhance gameplay, such as the ability to customize shots of each character, and new enhancement elements, such as Prism Gems, all aimed at ensuring players can continue to enjoy the game for the foreseeable future.

All online services will remain available after the "PARTY GOES ON!" season ends. In addition, we plan to hold the FOAMSTARS CUP, a series of in-game events named after each character.

Furthermore, to ensure that new players can fully enjoy FOAMSTARS, previous Season Passes will be made available again. Players can switch between Season Passes at any time to proceed along the Season Pass track of your choice and obtain items from past seasons. This will make it possible for players to obtain all the items from each season.

My sadness is immeasurable. I downloaded this game for PS+ and never played it. It's one of my top 100 games I've downloaded but never played. How could they do this to me?

Everybody saw the current live service collapse coming except, perhaps, the people making the games. Foamstars is staying up for now, so my fellow foamies can keep on foamin', but FOMO wasn't enough to foam up demand for this mediocre game.

There are only so many hours in the day, and so many communities that can be sustained.

Not unexpected but I am glad they are at least keeping it online. The game itself was not half bad, I played a decent amount of it when it was added to PS plus.
