To unlock the Kill or Be Killed trophy, you will need to kill one of the game's Monstrous animals.
There are four types of Monstrous Animals in Far Cry New Dawn:
- Monstrous Cougar
- Monstrous Bison
- Monstrous Bear
- Monstrous Boar
You will be able to recognise them when you come across one from the yellow health bar. Once you have recruited Bean, you can upgrade the Cartography Center at your base in Prosperity and buy maps to be given their locations.
The Monstrous Animals are the toughest enemies in the game, so it is recommended to use a legendary weapon to make the fight easier. Each Monstrous Animal will have a glowing body part. Try to hit that as it will deal more damage.
