TacHelium is a small YouTube channel consisting of a small handful of people. The main perspective behind the channel is Xbox One user TacHelium, who founded the channel back in 2015, but hadn't uploaded any content until early 2020. Most of his current videos include him and another Xbox user named KiwiYT. The channel itself focuses on ever-popular war game, War Thunder, though he has made a statement saying that "the subject of my channel is always changing, I've just never put it into effect."
