Leave the area and never come back…
If that’s not an option:
- Bird poop is flammable.
- Grenades are fast.
- Friendly turrets might help.
- A fungal outbreak would be fatal (both to the birds as well as to you).
- Currently there are more cars than (living) people in the world, and they don’t need wipers to keep the windscreen clean.
- Cheating ( / Debug Menu) has a kill all option or allows you to play “the floor is lava”, but comes with drawbacks (might destroy something you don’t want to have destroyed).
Looks like your baby chick has grown very well…
