One of the new breed of sci-fi MMOs that crosses a first person shooter with an MMO is Global Agenda from Hi-Rez Studios. For those fans of class-based FPS games like Team Fortress 2, Hi-Rez Studios has emphasized that TF2 has been a major influence on Global Agenda's development. While the game's release date hasn't been announced yet, Hi-Rez has been fairly active in terms of promoting Global Agenda. Hi-Rez Studios executive producer Todd Harris has written a dev blog for MMORPG.com titled "A Minute To Learn, A Lifetime To Master", a motto which is very much the spirit behind Global Agenda's game design.
Harris breaks down the major tiers of Global Agenda's gameplay as: Action/shooter mechanics and reflexes; RPG/build; Team tactics and cooperation - per mission instance; and Domination strategy and coordination - per alliance vs. alliance campaign. Harris goes into detail in each of these facets of the game, and explains how these tiers have played out with the roughly 1000 Global Agenda alpha testers.
