Titanfall 2 is now out- but unlike the original game, which emphasized its multiplayer mode at the expense of all else (it did not even have a single player campaign), Titanfall 2 places the most focus on the story that it tries to tell in its single player story mode. Respawn have attempted to build on their fantastic world with Titanfall 2, their campaign especially building up the relationship between a Titan and its pilot.
The campaign in Titanfall 2, then, is what you will be playing the most. It is what you are expected to spend your time on (even most of the Trophies/Achievements for Titanfall 2 are for the single player campaign, with only three relatively easier ones being attached to the multiplayer). The campaign, too, is unlike most modern shooter campaigns, recalling older shooters like Half Life 2 more than anything.
If it’s the campaign you want to play through, however, you’ll want and need help with it- and that’s where this walkthrough comes in. You can check it out below, it walks you through the entirety of the game, complete with the ending.
