Less of a battle and more of a test of endurance and skill, some might call facing The End boring. But either way, it is long.
This not-so-real battle requires you to tap into your stealth ability to face off against The Boss's mentor and world's greatest sniper in something of a snipe-off. But be careful - one wrong move can send you right back to the beginning. That's why this fight winds up being so long. It requires precision and patience, and if you don't have it, you're likely to end the fight early via rage quitting. But if you take your time, you're sure to get the job done within an hour or two.
