Ubisoft are running the stay at home promotion by offering games that are free to keep with three games whose free to keep status was meant to end during April 2020. It has now been extended into the first few days of the following month.
Rayman Legends, Assassin's Creed 2 and Child of Light were all free to keep on uPlay at the time of writing. All three games were already on free to keep promotion until early April 2020 for some and mid-April for others. However, Ubisoft decided to extend the offer until 5 May 2020.
In other words, you can pick up all three of these games until next Tuesday, despite each of them having had a promotion of their own already. Keep in mind that the promotion is valid only for PC and only through uPlay. Even though it's not among the most popular of launchers, free games are free games.
