Game title: Portal 2
Once upon a time, a secret laboratory hidden deep underground invented portals that allow people to instantly move between places despite the distance that separates them. Unfortunately, that created passages between dimensions and led to a lot of troubles. But our hero doesn’t know it yet. He ended up in the lab by chance and is only discovering the possibilities of portals. You need to help him find a way home without getting stuck in the endless spatial mazes and successfully overcome all the difficulties waiting for him in the process!
