Giant logs being pushed down a river by a single man.

The video begins with a man pushing large logs down a river. He then uses a rope to pull a log, and other people join in to help. The scene transitions to a man in a room, fighting off zombies. He then begins to build and upgrade the room, adding furniture like a bathtub and toilet, and eventually a garden with tomato plants. The game appears to be a survival/building simulation with zombie elements.
