FOAMSTARS
FOAMSTARS is a vibrant 4v4 online party shooter developed by Square Enix where foam serves as both weapon and terrain. Players battle across colorful arenas in competitive multiplayer modes or team up to tackle wave-based PvE missions. By laying down foam, you can construct elevated vantage points, block enemy sightlines, and surf across the map at high speeds to gain the upper hand.
