"Global Agenda: Free Agent" was a freemium-ish PvP arena shooter from Hi-Rez with a few problems. The game did have a lot of fans before Hi-Rez did what they do best and killed their own game.

Problematically Hi-Rez did the nasty thing of not using Steamworks and demanding users create an account and presumably hand over all kinds of personal info and "telemetry", this is possibly one of the problems that lead to the demise of the game.

Anyway, if you somehow get a Steam key for this, it's been pulled from the store, there's no servers, no players, so don't bother.

Game is dead. The streamer who made it spike briefly is just a phony and their followers are sheep.
