Combat in Apex Legends (above) is fast, but not Titanfall-fast.

Apex Legends is Respawn's new battle royale set in the Titanfall universe, but it's definitely not a Titanfall game. The first and biggest clue: There are no Titans. There are no big robots to control in this battle royale, and you're not playing as a Pilot, Titanfall's elite soldiers. That means Apex Legends is sadly also missing Titanfall's fun hyper-mobility, with no double-jumping or wall running at your disposal.
