Systems, methods and computer programs for delivering a multiplayer gaming experience in a distributed computer system
A multiplayer software “wrapper” is provided around a conventional single-player modality game. The wrapper allows multiple players, each with their own player device, to share a common multiplayer game session. The single player game is hosted on a game server and is coded to support only a single player device. The wrapper provides a multiplayer interface to the single-player game in a way that does not require any modification of the underlying game code or game server architecture. A centralized and automated gameplay system sits between, on the one hand, the multiple player devices and, on the other hand, the gameplay server hosting the single player. The gameplay system collects game instructions from multiple player devices and determines single-player inputs to the game based on the game instructions from the multiple player devices.
1. A computer-implemented method of delivering a multiplayer gaming experience by a gameplay system, the gameplay system in communication with a first player device and a second player device, the method comprising:
establishing a multiplayer game session between the gameplay system, the first player device and the second player device;
transmitting a game initiation message from the gameplay system to a game server, and thereby causing the game server to initiate a single-player modality game associated with the multiplayer game session;
receiving at the gameplay system a first game instruction from the first player device;
receiving at the gameplay system a second game instruction from the second player device;
transmitting to an account provider system one or more validation messages indicating the first and second game instructions for validating the first and second game instructions based on first and second player accounts associated with the first and second player devices respectively;
receiving from the account provider system one or more validation responses indicating whether the first and second game instructions are valid;
based on the one or more validation responses, determining a shared game parameter from the first game instruction and second game instruction for the single-player modality game;
causing the shared game parameter to be transmitted to the game server, the shared game parameter forming a single-player input to the single-player modality game;
receiving a game result from the game server, the game result having been generated at the gameplay server by implementing a game action in the single-player modality game based on the shared game parameter; and
communicating the game result from the gameplay system to the first player device and the second player device in the multiplayer game session.
2. The method of claim 1 , comprising:
associating a session account with the multiplayer game session, wherein the session account is indicated to the game server, and is accessible to the game server for validating the shared game parameter; and
updating the session account based on the one or more validation responses received from the account provider.
3. The method of claim 2 , wherein the game result received from the game server indicates that the session account has been updated by the game server, the method comprising:
responsive to receiving the game result, accessing, by the gameplay system, the session account as updated by the game server; and
transmitting, to the account provider system, one or more update messages based on the session account as updated by the game server, the one or more update messages causing the first and second player accounts to be updated.
