In the second region of Death Stranding 2, players will come across various types of BTs and Chiral creatures scattered across Australia. Some of these Chiral creatures are non-hostile, while others will try to attack you whenever you get too close. One of these is the Bats, usually found flying in large groups near the shores.
These Bats deal damage to both Sam and any vehicle he might be riding.
Dealing with them can be extremely frustrating, as using ranged weapons like an Assault Rifle isn’t particularly effective. Here is what players can do against the Bats in Death Stranding 2.
As you cannot rely on using ranged or melee weapons against the Bats, you will need to use grenades.
The first ones you come across are the Blood Grenades, which unlock after completing Order 4 and connecting C1 South Distribution Center to the Chiral Network. The next useful grenades for the Bats are the MP Grenades, which unlock after completing Order 10.
Once these grenades have been unlocked, you can place them in your grenade pouch and prepare for your encounter with the Bats.
Upon coming across a group of Bats, before they get too close, equip the MP Grenades from the Weapons/Tool wheel. Aim and throw a grenade on the ground near you as the Bats approach—this should kill them all in a single explosion. If there are a few stragglers left, you can ignore them and proceed with your delivery.
A Blood Grenade works similarly, but you can throw it directly underneath you and stand inside the mist for a few seconds while the Bats start to dwindle in number.
Fabricating Blood and MP Grenades doesn't cost much, and you can also find them occasionally as cargo to pick up or inside the Shared Cargo feature at Safehouses or Distribution Centres.
Here is the fabrication cost for both of these grenades:
