Hitman is a deadly game. Every other object in it can be used to murder someone in some way. But, even in this deadly world, there are objects Io Interactive determines are too deadly, like a toilet in Marrakesh.
According to the patch notes of Hitman's latest update, Io had to fix the toilet in the school area of the Marrakesh level because it would sometimes "behave erratically." Apparently, on rare occasions, after Agent 47 kicked the toilet through the whole in the second-floor room onto the target Zaydan below, the hitman could end up being killed.
I mean, we've all had difficult times in bathrooms but that seems excessive, 47.
