The eagerly anticipated mech shooter Titanfall will not feature any mod support when it launches March 11 on PC and Xbox One/360. Respawn Entertainment co-founder Vince Zampella confirmed the news on Twitter a few days ago.

There may still be hope yet but for the moment Titanfall will be strictly vanilla flavoured on release.
