At their GamesCom 2015 conference Microsoft announced that a sequel to 2009’s Halo Wars is being produced by long time RTS developer Creative Assembly. The folks over at CA are probably best known for the Total War series but they also developed the critically acclaimed Aliens: Isolation this past Fall.
Very little is known about the gameplay or story for Halo Wars 2 aside from the fact that Creative Assembly have said that the game will play closer to the original than their other RTS titles. The 2009 original focused on UNSC “Spirit of Fire” and takes place 20 years before the events of Halo: Combat Evolved.
Halo Wars 2 will be released for Xbox One and Windows 10 in the Fall of 2016 according to the trailer released during GamesCom.
