14 More Secret Video Game Bosses You Never Knew Existed

So Sorry – Undertale

Undertale is a game that’s filled with interesting details for eagle-eyed gamers to find, case in point – the So Sorry boss fight. To initiate this boss fight, you will have to travel to the Art Room and then read the sign at a very specific time frame (8:00 – 8:59) when the computer clock is set for October 10th. A point worth noting is that the only way to defeat this boss is by killing, so it might be best to avoid the fight altogether if you’re aiming for a True Pacifist run.
