Let's cut to the straight dope on Titanfall as by now, if you don't already have it, you know what it is. It's for now, the killer app for the Xbox One (and PC) and it's supposed to re-invigorate the stale shooter market, which it does in varying degrees.
So rather bore you again with what it is and how it plays, I will just stick to my experience with the game.
So, of course you have a tutorial that you have to go through to access the rest of the game and while for some, it may seem like a pain to go through as many of us undoubtedly have played shooters, this one to me was very helpful considering there are small nuances that differentiate this over other shooters. If done correctly, you can be finished in about 15 to 20 minutes and from there, you can play the campaign.
The campaign itself is very forgettable and contrived and to be honest, I really don't remember much of it as I played. The thing is, the campaign itself makes us the player, more of the background for the main characters and the outcome of your match really doesn't change it one way or the other how you progress in the game. I mean if you lose the campaign, it's not like you have to start all over or suffer some kind of penalty for losing. I can say this, as a multiplayer campaign, the main thing I was worried about as far as system lag or dropout never affected my gameplay and my online experience was smooth. If I had any complaints about the campaign mode was how unbalanced the teams were. Rookies seemingly were always on the Militia side as more experienced players were on the IMT side. But I really don't think anyone cared. Not to mention, there wasn't a lot of variety in the matches played during the campaign as you mostly play attrition and 1 or 2 domination matches.
