A round of Attrition in Titanfall is kind of like eating a three course meal. For starters, you'll mop up a few of those AI-controlled Grunts or Spectres to accelerate the arrival of your Titan: each AI extinguished equates to a few seconds off the clock. The main course consists of sticking it to other Pilots - dropping onto them from above with a loaded shotgun, snapping their necks from behind, tossing grenades through windows and what have you. And dessert? That would be when the Titans show up. As mother used to say, you can't have your pudding till you've polished off your vegetables.
