At the time, we were working on Titanfall 2, and we had BT, which is Buddy Titan, in Titanfall 2, so I just penciled him in as Buddy Droid, Buddy Droid-1, and it just stuck. When we made what I would call like our one-page of what the game was, I wanted to have a droid in the game as kind of a companion to Cal that would help him not only by keeping him going mentally when he was out in the wild, but also provide really important features and mechanics. Is there a story behind the design of that character? Cal also has a cool new droid helping him out, BD-1.
