Bad Day LA is a post-apocalyptic action game with unusual mechanics. This game has a crowd-to-player relationship system. The more good deeds he does, the better people around him treat him, but if this indicator becomes too low, they will turn into his enemies. People, as if by herd instinct, will begin to attack him, beat him and try to eliminate him.

The main character Anthony was a former special agent and worked for the government, but after some events he became homeless. And when the world needed him most, he wasn't there. Wrong by accident or intentionally, the transportation of nuclear waste failed and ultimately turned into a disaster. The world began to change, living beings mutated, and due to a virus leak, the dead turned into zombies. Now the man has to get out of the city to a safer place and meet a variety of characters along the way. They can become his allies and help in battles or, on the contrary, a strong hindrance.

In Bad Day LA, the player must complete various missions in each level and ultimately save the world through his actions. Perhaps there is a cure for the undead invasion and a chance to return them to their former lives. But who knows what price the guys will have to pay for such a grand discovery and how it will turn out for everyone in the end. After all, not all heroes are destined to survive and then receive an award in front of the president.
