Some “Recognition Medal of Self-Resistant” rotate around it (can be killed but medal medal respawn them after some time). They have 300 hp each
A “Greatest Chicken Hunter of All Time Award” is chasing you (unkillable)
“Chicken Hunter Medal of Excellence” fall as meteors, splat at the bottom of the screen as “Medal of Great Appetite Achievement”. Their direction and angle change each time they come.
At 75% damage the boss goes enraged:
Medal medal moves faster and “Chicken Hunter Medal of Excellence” falls from 2 directions at the same time.
Also a second “Greatest Chicken Hunter of All Time Award” spawns every 25% damage dealt
Well… there aren’t, but since no one else agrees with my point of view that achievements are something else than medals I used their point of view. And you have 4 achievements in Steam Version of CI2.
