One of the opponents encountered in Death Stranding is a giant which is simply called BT. The hero sees him at the beginning of the story. However, we face this enemy in chapter 9.
You encounter this monster in the ninth chapter, during order #63.
The enemy is giant and very tall. However, it has very limited movement which makes it an easy target. The ideal weapons to fight it are Hematic Grenades, Remote-Detonation Grenade Launcher and Anti-BT Handgun.
If you have a rocket launcher, aim for the giant's chest. This way you will the biggest damage.
Each attacked body part will turn red. You can focus your fire on the bleeding parts.
The giant is very static. However, it can attack you by sending other BTs. Avoid them.
If you do not have a rocket launcher, try using Hematic Grenades. They are perfect against BTs.
You can throw grenades at the enemy's feet. Thanks to this, you won't risk additional damage and you will be able to constantly attack the enemy.
The giant isn't difficult. You only have to avoid BT and find the right moment to attack. A few successful hits should be enough to defeat the monster.
