10 UN-WINNABLE Video Game Fights (You Can Actually Win)
5. Overboss Colter - Fallout 4
The Nuka World DLC for Fallout 4 begins with the Sole Survivor getting trapped inside a deadly gauntlet and then fighting a raider boss, Colter, who uses a special electrified power armor, making him impervious to all damage.
The way the game wants you to defeat Colter is by using a Thirst Zapper squirt gun that one of his lackeys left in the room leading to the duel arena. The water breaks Colter's electric defenses, stunning him and allowing you to deal damage.
However, as it turns out, Colter's invincibility isn't all it's cracked out to be. Though the game wants you to believe Colter cannot be defeated without the water gun, his armor has a secret threshold of damage it can withstand. If you have a weapon that can deal a lot of damage really fast, Colter can be wounded even in his invincible phase.
Of course, defeating him like this is an exploit, so you don't get anything from going the extra mile and never touching your free-win squirt gun... other than the satisfaction of breaking the game.
