UNRELEASED GAME - CANCELLED
This game was cancelled in development.
Unlike other prominent collectible card games in the genre, which are played in turns, Titanfall: Frontline is played in real-time. The player collects and places Pilot, Titan, and burn cards to damage and defeat their opponent. Pilot and Titan cards can combine to perform extra damage.
Titanfall: Frontline was cancelled on January 13, 2017 as "the experience wasn't ready to deliver the intense action-packed gameplay synonymous with Titanfall. While it's never easy to cancel a game, we're excited to take some of the concepts we saw resonate with players and build off of them in future Titanfall mobile games,".
