Ubisoft is hosting a launch livestream for Assassin's Creed Unity, and one of the funniest event was a "race" done using the game's co-op mode, during which the four players had to reach the top of the spire of Notre Dame in Paris without touching the ground.

The "race" is really funny to see, and looks like it was actually quite fun to play.

To add to the fun, we can also see a couple funny glitches. At 7:35 the red player faceplants on the cobblestone, and the impact is so violent that the rag doll physics of his body go awry and and he starts twitching like a zapped eel.

At 9:40 the yellow players reaches the plaza in front of the destination and jumps on the ground from a cart, only to fall into an unpredictable trap. A glitch makes him fall through the ground to his demise. It's actually quite hilarious to see how the hosts try their hardest not to mention what really happened.

Of course we also have to keep in mind that glitches in open world games are nothing new or surprising, considering the size and complexity of the world.
