Is it called Halo 5 yet? What is this game even called. It's so secret that it doesn't have a name yet. Probably has a codename like 'HALO: HEXAGON' or something like that. Anyway, 343 Industries just released a brand new piece of concept art for the game. It tells us nothing, shows us nothing, yet somehow made me feel a little bit tingly inside.
So, as far as I can see it has Halo-style spaceships, set in a Halo-style cityscape. It looks 'dark' and 'moody' and may be the setting for some sort of night mission. It may also just be a cool drawing one of the concept artists drew on his lunch break, but hey — why ruin a fun little bit of speculation.
But if you're looking for actual concrete information on how Halo 5 is progressing, you might as well head to the blog post where the above art was revealed. Interesting stuff.
