There's a new version of Titanfall out on Origin right now, which packages up the game and its Season Pass for a very reasonable price.
Yep, Titanfall: Deluxe Edition includes every single one of the game's existing map expansion packs; Expedition, Frontier's Edge, and the recently released IMC Rising.
Proof that's it's usually best to wait a few months if possible for the best deal, you'll be able to hold of the Deluxe Edition for $39.99. That's very reasonable. I've never been enamored with map packs for multiplayer shooters, which tend to cost far more than they feel like they're worth, but this seems like a much fairer deal.
