Game Fuel (Mango Heat) was a Mountain Dew flavor that was released in October 2016. It had been taste-tested at select college campuses in late 2014 under as a vault flavor the name "Mango Habanero," alongside two others, Dewitos and Lemonade with Ginger. When it was released two years later, the flavor (alongside Citrus Cherry) was released to promote Titanfall 2, breaking the 2 year Call of Duty promoting streak set with 2014's Lemonade Game Fuel and 2015's Berry Lime Game Fuel. Its tagline was "DEW with a Blast of Mango Heat Flavor with other natural flavors."
Game Fuel (Mango Heat) was a mango flavored soda, with a weak ginger finish and orange color.
Mango Heat was released for a limited time exclusively at 7-Eleven stores in Canada in April of 2017, in 16oz cans and Slurpee. It had none of the usual Game Fuel branding that its American counterpart had, instead, it had the standard Mountain Dew branding. This is the only time a Game Fuel flavor released outside of the United States.
