15 Longest Boss Fights That Will Take Hours On Your First Playthrough

Senator Armstrong – Metal Gear Rising: Revengeance

The fight with Armstrong is tough when Raiden loses his sword, meaning you have to whittle his health down to 90 percent and then intentionally take a hit. However, that means parrying his attacks, dodging the unblockables and fighting back accordingly (which will probably lead to death more often than not, especially on Revengeance mode). Once you’ve got that part down? Then the boss battle begins in earnest.
