A free trial is available on Steam, letting you play characters up to level 15. Global Agenda requires Steam as it uses auto-updating and other Steamworks features.
While Global Agenda's previous $12.99 monthly subscription was optional, those who didn't pay it found their game more than a little restricted. Subscribers gained access to the alliance vs. alliance 'World Domination' mode, the auction house, crafting, in-game mail, improved communication and more, not forgetting character levels beyond thirty.
"Future content updates will be delivered via optional paid expansions," Hi-Rez explains, to support the game. One such expansion, named 'Sandstorm,' is being released for free in two parts this summer to give players a freebie taste of the new way.
