Devil May Cry 3 HD

After defeating Vergil (the final boss), the credits will roll. And while they are playing, demons will appear, you need to kill 100. Use Agni and Rudru or Rebellion. A lady will help you. The demons she kills will also count. The 100th demon will be the first boss in the game.

From small arms, put an anti-tank rifle (spiral) and from a close-range rebellion, hold down the sight, and take turns shooting from the cannon, then make a stinger with a sword and so on until you’re blue in the face, I hit up to 400 enemies on easy difficulty on PS2
