Chemz.io is a superb multiplayer action game you should try. Slightly critical of contemporary aluminum hat culture, this game is ultimately motivated by conspiracies around chemtrails.
Your main goal is to poison as many people as you can while circling around on your plane. You can poison people and your plane will be larger the more coverage you have. Moreover, you must gain weaponry, speed boosts, and temporarily larger wings by gathering power-ups to poison more people.
On the other hand, be mindful that some will attempt to harm you in order to obtain your coverage. A bigger plane will be yours when you kill a player and inherit all of his coverage. In an effort to poison them temporarily as well, you should try to entice other individuals to fly into your chemtrails so they can utilize yours rather than theirs.
