Somerville begins with an alien invasion of hostile creatures. They set themselves a single goal — the destruction of people and the appropriation of the territories of our planet. The player will control the father of the surviving family. A man saves his relatives from the attack of deadly creatures. The goal of the task will be to go from the starting point to the final goal. The path will not be easy and dangerous, because everywhere is full of traps from uninvited guests. You can play as any of the three family members and their pet.
