It was almost a year ago that we began hearing about the first game from Respawn Entertainment, the company founded by Infinity Ward co-founders Jason West and Vince Zampella, who were summarily fired by Activision in early 2010 despite delivering consistently sterling results (sales wise, at least) on the Call Of Duty franchise. Ever since, the pair have talked up the idea of building a game that would be a "Call Of Duty killer", a phrase that the gaming press has latched onto when hyping up Titanfall, the duo's first game under the Respawn banner. You may have read our impressions of the beta released last month, where it seemed to be the case that Respawn had made a fun if not particularly revelatory FPS. Having spent the last few days grinding away on the final product, however, that tune has changed somewhat. Yes, Titanfall still has sub-par visuals (even on "Ultra" settings on the PC), the rounds need to be longer, the multiplayer campaign is a sucky embarrassment and it could do with more customisation and match types, but all that said, it is an outrageously entertaining experience. With its fast pace and weighty combat, this is significantly more fun than Call Of Duty has been in years and years. Battlefield may still have the last word when it comes to superior multiplayer mayhem, but Titanfall is a mighty beast itself, and has dropped an awesome payload on the creatively exhausted COD franchise. If you've been playing it so far, what are you making of Titanfall? Let us know in the comments!
