I felt like these bosses were missing something, and then it occurred to me that when one enemy from a boss battle dies, another should get angry because you killed his brother
(when boss get enraged he makes the same sound as when he dies, the screen will shake and the same effect will appear as when you shoot the assassin chick)
enraged Twice Infinity:when one infinity chick dies the other will start
healing, become faster and have a new attack (it will fire orange projectiles 3 times (the trajectory of the projectile is shown in the picture))
enraged show them who’s the boss:every time one chicken dies the others will get a little bit faster and when there are three chickens left they will start healing
enraged Brothers Reunited:when the party chicken dies,military chicken will become a little faster,he will start healing and sticky bombs will be thrown(if you get too close the bombs will explode after half a second and
it will also stick to the ends of the screen)
if the military chicken dies, the party chicken will become a lot faster, he will start healing and will have the same attack as the last phase of CI2 mother hen ship only with more projectiles
