Respawn recently released the new cooperative Frontier Defense mode for Titanfall 2 and it seems to be a smashing success. In an interview with Gamespot, CEO Vince Zampella said that there are two or three as many people playing Frontier Defense than all the other multiplayer modes combined.
Zampella also said in no uncertain terms that Respawn is already working on more Titanfall and, as a studio, they are heavily invested in the IP.
The game was successful, it sold well, but it didn't quite sell as well as it should have. Maybe because it was super crowded, the pricing was aggressive--it was a rough window to launch our game. But we've got a really great fanbase. There's not really much negativity or acidity compared to other communities, so I'm very thankful for that. It's important for us to keep the franchise going. "We're doing more Titanfall," which is the quote I'm supposed to say. We have our franchise creative director, who's in charge of safeguarding the franchise in multiple formats and making sure it continues to grow. There's some other things we're doing that haven't been announced just yet, but we're heavily invested in the Titanfall universe.
We're very proud of what we have so far. As a new studio, we tried something different and new, and while it worked--maybe not well enough to remove the single-player--we kinda expanded with the follow-up, and we brought in the single-player, which turned out great. We're working on more Titanfall--we're not announcing what that is yet, but there's a few other things in the works--the mobile game, which turned out fantastic and is super fun, the fans love it and allowed us to expand on what we did in the last games. So I'm pretty happy with what the franchise has become.
As a reminder, Respawn is also working on a new Star Wars action/adventure game.
