Raid Rush

Raid Rush is a co-op boss-fighting game on Roblox where you and up to seven other players team up to hunt down powerful bosses across different realms. You get flashy abilities, magic, and cool effects to take down massive enemies. The gameplay loop is all about grinding: defeat bosses, earn resources and loot, and use them to get stronger for the next round! There's a passive progression system, so even when you're losing, you're still getting progress!
