Titanfall on PC will not support mods or offer any map editor tools to players at launch. Respawn Entertainment co-founder Vince Zampella confirmed as much on Twitter, though he did say that the studio "will have to evaluate after launch."
Former Infinity Ward heads Jason West and Vince Zampella were dismissed by Activision in early 2010, spurring a lengthy legal battle between the duo and publisher. The two would quickly go on to form Respawn Entertainment, partner up with EA and begin work on Titanfall.
Titanfall launches on March 11, 2014, exclusively for the Xbox 360, Xbox One and PC. While Titanfall will remain exclusive to these platforms throughout the lifetime of the game, Respawn has said it plans to develop games for PS4 down the line.
