343 Industry remained expectedly tight-lipped on Halo 4 details at the Halo 4 panel at PAX this weekend, but did reveal that Halo 4 will be the first game in a so-called 'Reclaimer Trilogy'.
Details are scarce, but speaking at the presentation, 343 Industries' Frank O'Connor did reveal: "This trilogy is a direct continuation to the events in Halo 3. It will deal with the fate of John and the fate of Cortana."
A 'Reclaimer', according to sites that love Halo more than life, is someone who's in charge of activating a Halo super-weapon. Speculate over that if you will.
O'Connor also promised that players are "definitely going to have the opportunity to dive deeper into John's (Master Chief's) mind in this trilogy," hinting at a heavier focus on narrative this time around.
343 released a new Halo 4 video today showing off some of the dark and mysterious concept art work for the new game. Well worth a look.http://www.computerandvideogames.com/317121/halo-4-is-first-in-the-reclaimer-trilogy/
