The following information will be passed to the game server allocated by the Matchmaking system:

• SessionId - The SessionId for the server will be equal to the MatchId for the match.
• InitialPlayers - This value is set to the list of members in the match. The list of players can be read in the game by using the GSDK.
• PreferredRegions - This field is set to the RegionPreferences field from the match. The game server service will choose an appropriate region for the server from this list.

They can be retrieved using the GSDK, more details can be found here: https://docs.microsoft.com/en-us/gaming/playfab/features/multiplayer/servers/integrating-game-servers-with-gsdk#csharp-4

InitialPlayers contains a list of members’ title_player_account_id in the match, which looks like the following:

"initialPlayers":[

"title_player_account!FC150DAFC86B9C13",

"title_player_account!C59F8D70E9FDC89C"

]

You can use such info to retrieve the player’s title data. Assuming that you need to use the GetUserData API to retrieve them, which uses the PlayFabId (master_player_account_id), for that you’d need to use GetProfiles to retrieve each player’s PlayFabId, they’re in Profiles[x].Lineage.MasterPlayerAccountId: Account Management - Get Profiles (PlayFab Profiles) | Microsoft Docs

The flow above may seems a little bit complex, to simplify this, you can just have the players specify the weapons they’re about to use in the “Attributes” property when creating tickets, and on the server side, use GetMatch with the aforementioned SessionId to retrieve such info.
