Seriously, why are you still here? All the DLC for Titanfall is currently free on Xbox One and Xbox 360. Just go online and get it. FREE.
You're probably gone now, why would you still be reading this? I can say whatever I want. Flummox.
It's not currently certain why the DLC is suddenly free–the season pack usually costs $24.99–but Polygon have mused that it probably has something to do with Titanfall being released a year ago today. You'll still have to pay on PC, sorry master race :(
