Armored Core 6: Fires of Rubicon - 13 Minute Official Gameplay Preview

I've never played an AC game, but a huge fan of the Souls games. I'm not sure what to make of this - but I have a lot of trust in From, so I'll almost certainly pick it up.

I like how complex it looks, and the bosses look crazy. From Vaati's video it looked like there were 11 missions though... does anyone know if it's just those plus the arena? I don't typically replay games once I've finished them (game time is limited)!
