No Season Pass required: all maps & modes will be free in Titanfall 2 Multiplayer. This means no splitting up the community and it all starts with the legendary Angel City map, remastered from the original Titanfall. This means once you’ve purchased Titanfall 2, your investment includes a full single player campaign, the full multiplayer maps and modes, and long-term support with no hidden costs. You can pre-order the game to play 3 days early, but it will never cost you extra.
Now, don't go thinking that means there won't be microtransactions: Respawn Entertainment has admitted that there will be those. However, they will be cosmetic purchases only, and as they made clear in the quote above, anything that effects gameplay will be free for everyone. It seems they've put their lot with other massively successful games, such as Overwatch and Splatoon, in that regard. Oh, and Uncharted 4: A Thief's End did it as well.
That's pretty dope, at the end of the day. Think what you will of Titanfall 2 (and if you're a reviewer, chances are you think quite highly of it) but this kind of customer-first approach is something we should applaud. And see more of. Lookin' at you, EA.
