Battle Arena In Desert

A military gas was scattered over the city, and everyone has gone mad. Rage in the soldiers increased several times, everyone who had a weapon started shooting right away. You are the only one who has not inhaled the gas. Destroy all the sick or hide. The main goal is to hold out until reinforcements arrive.
