Flock jokes about alien abductions and builds the entire gameplay around this idea. This is an isometric puzzle game in which the user controls a UFO. A flying saucer steals farmers livestock. Everything happens in real time. There is a local co-op for two. Flock consists of 50 puzzles. Their number can be increased using the level editor. The selection of maze-like stages is carried out on the global map. The user’s task: pick up all the animals from the pens or pastures and bring them to the mother ship before the timer expires. Sometimes the game throws up additional humorous tasks. For example: make sheep mate to get more animals.
