Let me see if I can put down what I remember.
Next year we will see MWO drop a new Game mode called SOLARIS 7, each season has a 3 month run time, can be played as Solo (still think it's not versus Enviroment, but 1v1) or 2v2.
As you play you can earn/lose Sponsors and Contracts.
Ass sorts of new items for mechs( cosemetic only but consist of things like SPIKES, HORNS, and the mech in the video ended up wielding a HATCHET!
At the end of the season, the standings are recorded in the archive and the new season begins.
NOTE, the SOLARIS 7 is a new game mode (like Solo Play and Faction Play), and there is a new Map coming called SOLARIS CITY, looks cool, has a lot of funky neon lights etc, think battling in DownTown Las Vegas!
