This page of the Dying Light 2 guide has information on the Red Gas Tank. We explain how to use gas tanks and where to find them.
Red Gas Tank - where to find it?
Gas tanks can be found near the military convoys, bandit camps, GRE Quarantine Buildings, anomalies, and other side activities in the game. Sometimes the gas tanks are placed in the mission area related to the main storyline, most often during fights with a larger group of enemies or bosses. Single gas tanks are sometimes even found in city streets.
Before entering a fight or clearing the place of the infected, you should thoroughly search the area first and find all gas tanks and other temporary weapons using Survivor Sense.
Gas tanks can sometimes be hidden or not visible, but they have a characteristic shape. Thanks to thoroughly scanning the entire environment, you will certainly discover all gas tanks that will allow you to eliminate larger groups of infected faster.
Red Gas Tank - application
Gas tanks can be used in several different ways. You can first ignite the tank by holding down the appropriate button and then throw it at a group of enemies and eliminate many infected.
You can also place the found gas tank anywhere and lure opponents near it, for example, by tossing a coin that will make a noise, drawing the attention of nearby enemies.
Once the enemies approach the gas tank, use a throwing knife or another ranged weapon to ignite it. It will explode after about 5 seconds, eliminating all infected within its range. Additionally, the noise will lure other opponents, giving you a chance to escape without being noticed.
