As you're most likely aware, the Norte-Dame cathedral recently had a catastrophic fire that caused significant damage to a building that was already in need of renovation. In order to ensure the Norte-Dame returns to its former glory and opens its doors as quickly as possible, numerous companies and individuals have started pouring considerable amounts of money into a restoration fund, including Ubisoft themselves.
"As the smoke clears on the events that unfolded on Monday at the Notre-Dame de Paris, we stand in solidarité with our fellow Parisians and everyone around the world moved by the devastation the fire caused," reads the official announcement. "In light of Monday's events, we will be donating €500,000 to help with the restoration and reconstruction of the Cathedral. We encourage all of you who are interested to donate as well."
Additionally, Ubisoft is currently giving away Assassin's Creed Unity for free on PC, so if you ever wanted to visit the Notre-Dame, this would be a pretty good alternative until the real deal has been fully restored. The one catch is that the whole event will only last until April 25th, so do make sure to grab yourself a copy as soon as possible.
And just for good measure, allow me to leave you with one of the original trailers. Enjoy!
