Announced about a month ago and following a beta back in September, FOAMSTARS is now out, but only through Playstation Plus. The game does not actually have a standalone purchase option at this time but is exclusive to Sony's monthly subscription service as one of the free games for February. Once this month's rotation ends, it will go on sale for $29.99 in March.
FOAMSTARS is a first person shooter where you sling foam instead of bullets, both dealing damage and transforming the arena on which you play. Each team uses corresponding color foam and you get buffs or debuffs depending on which you are traversing. There will be free themed seasonal updates throughout the year, and a Premium Pass for $6 to immediately unlock new characters and cosmetics for each season. Season 1 features the following events:
