Titanfall, the already popular first person shooter that includes large mechs is getting even more popular with this announcement on Twitter. Respawn co-founder Vince Zampella confirmed that future multiplayer modes will be released for free, and not tied up as part of expansions.
@YaBoyZD3 Modes we release will be free to all, not part of DLC.

This means that all modes released for the game will be free to all and not part of DLC packs, presumably these will still be charged.
