Rocketbirds: Hardboiled Chicken

This trophy can only be obtained for levels in a row and not for switching through the necessary chapters, and so the method of obtaining is simple, I personally started from the 8th chapter, there on two dereships you can zombify many of the necessary penguins,

Chapter 8:

1 is an elite penguin, he has a blue uniform and an armband.

2- a penguin with a rocket pack, he is in a red uniform.

3- penguin with a bazooka, in a white uniform.

Chapter 10:

4- penguin with a shield and baton, in green uniform.

5-row penguins are found not only here, but throughout the entire game they are your main enemies.

Chapter 12:

6 - an elite penguin with a shield and a baton, he will have a blue uniform, before the very end of the level he and another penguin will go down the elevator, it is better to kill the penguin with a machine gun, and the elite one with a shield must be zombified.

Chapter 15:

7- Zombie Putzki.

Remember that the levels must be completed in a row. So start from the 8th chapter until the last one. If you have already completed the game, then this trophy will take you 1-2 hours.

Everything was described perfectly by sadnemesis in his tip for the PS3 version of the game.
