Your game can be multiplayer from day one. Summer runs a server for every match and brings players together through matchmaking. It also keeps their progress, ranks them on leaderboards and runs your store. You don’t rent or manage any machines. Describe the game you want, and your coding agent builds it with Summer’s skills. Eight players joined to one World that Summer runs, surrounded by what Summer provides: servers, matchmaking, parties, saves, leaderboards and a store.
