BINARY DOMAIN

This is unlocked after destroying the Tsar Runner in Chapter 4-4. The Tsar Runner is ridiculously durable; expect the fight to go on for at least 10 minutes.

When the fight starts, focus your fire on the arms and head. Strip off the armor on all three. Once you can put two clips into either one without any more falling off, go to the next part. Once all three are weakened, choose an arm and keep shooting until it catches fire. A cutscene will trigger, and you'll move to the next part of the fight. Take out the other arm, then focus on the head.

If you start taking hits from the other robots, go ahead and take our their transports. They will respawn shortly, but it will buy you some time to regenerate your health and make aiming easier.

Whenever you get down to less than 250 bullets, Shindo will restock you. He'll also give you rockets if you have the rocket launcher, but the hit detection with it is terrible in this fight.

When the Tsar Runner rears up from behind, aim for the weak spot where its legs connect. When it rears up from in front, aim for its face. Leaving the face for last seems to help with hit detection to avert its attacks.

The Tsar Runner will also regularly fire one, two, or eight of the world's slowest missiles at you at a time. Make sure to take them down as soon as they appear. Too many hits from the missiles and melee attacks will destroy your truck.

If an arm has been destroyed, it will try to smack you from the side. Just aim for the good arm to stagger it.

Once all three are on fire, it will attempt to crush you from behind again. Just keep aiming for the robo-groin and it will stagger ever time. Eventually, it will go into a roller-blading animation and crash.

This is story related and cannot be missed. This one will test your patience. You will encounter a boss Tsar Runner. He is a yellow motorcycle looking transformer. You will have to shoot armor off his arms and head. He will shoot you with rockets. Good thing is they travel slow and you can shoot them out of the air. Continue shooting his arms and head and his weak spots when prompted. It takes alot of damage and what seems like forever to kill him. Do not let the truck take too much damage or the mission will fail. After he shoot the rockets, unload on arms and head until you see the glowing blue under his armor. You will get a checkpoint after he shoots 8 rockets at you at one time and a small cutscene. Pay close attention to the rockets and what Shindo tells you about the damage to the truck. Dont worrry about ammo because when you run low a prompt will come up for more ammo. Dont worry about shooting the green guys that fly around him. Just concentrate on shooting his arms and head. Another suggestion is go into your nano set up and put your health as high as you can. Also make sure to upgrade weapon every chance you get. The Tsar Runner is one of the hardest bosses in this game. Good luck.
