12 Video Game Bosses NOBODY Was Ready For

Contra has always been known for his its brutal difficulty, especially while battling the unforgiving bosses. So, when fans played Contra III: The Alien Wars, they expected to get frustrated, impatient, and angry.

But while blasting through this classic run-and-gun platformer, nobody thought they would get dizzy. However, that's exactly what happens in Level 5 when our heroic commandos encounter a cycloptic organism called the Anthell.

At first, this bulbous abomination doesn't seem too bad. By strafing around the centipedes he sends out and blasting his eye, Anthell should be dead in no time.

But after a few seconds, the sand starts shifting, spinning our heroes around. Within a few seconds, the player won't know where they are or where to aim, which usually causes them to walk straight into the boss and dying.

But Anthell isn't just hard, but disorientating. Watching the screen whirling round and round is enough to give anyone a headache.

Strangely, this bout is harder while playing with a buddy. Although you'll have twice as many guns, looking at two screens rotating at top-speed is sure to leave you feeling nauseous.
