Devil May Cry 3

the infested tanks are a pain in the arse to beat but they do have a blind spot, right under the turret, and because they are big and wide, they also shield you from the other tanks that are also firing at you, then after that you have to fight an infested chopper three times, you have to keep shooting at it because it is to high up for you to slash at it with your sword, but there is definitely worse bosses on dmc2 than there are on 3 and 1
