Titanfall 2

Story related, cannot be missed.

Cooper's Logbook:

Found Anderson, KIA. We're now responsible for finishing his mission. The IMC recently conducted a weapons test against a moon of Typhon, shattering it. It's called a Fold Weapon. The one we saw was just a "small" prototype. They're going to use a large-scale version to target Militia controlled planets, forcing us to surrender the Frontier. The planet Harmony is first on that. We have to get this Intel to Militia Command. BT says an IMC interstellar Beacon could do the trick.

    After killing Richter, enter the control room and disembark from BT to speak with Militia Commander, Sarah Briggs.

Defeating Richter:

Richter pilots the Tone Titan Loadout and he's very good at long range combat. Richter has shields similar to both Kane and Ash's shield regeneration abilities. The Ronin Titan Loadout is recommended for getting close and personal against Richter, but if you do get close you need to be careful of his Tracker Cannon and Tracking Rockets. If you need to take cover, try using the rocks around the area to do so or use Phase Dash [] to get away from the incoming rockets. Using Ronin’s Sword Block [] will reduce any incoming damage. Ronin can dish out heavy damage with melee.

Whenever you take down Richter's shield, press to use your Sword Core Ability to deal heavy damage towards him as quickly as possible before it ends. You need to actively swing the broadsword with or else you've wasted the Sword Core Ability. If you need to get Health, use the Dash [] to get to the green Health scattered around the battlefield. Dashing is also good for dodging most of Richter's attacks. If you need to, you can also perform a melee execution on Richter once his Health Bar is very low by getting close to him and pressing . Melee is one of the best-recommended methods to defeat Richter as quickly as possible. Some people might consider Richter the second hardest boss fight in the game, especially if you try to fight him with long range methods.
