"Run 2" is a game playable via a variety of game hosting websites, including Kongregate.com and CoolMath-Games.com. The game runs inside a browser window and thus requires an active Internet connection and the browser plug-in Adobe Flash Player.

"Run 2" is widely available on several game hosting websites for free. This three-dimensional running game tests a player's reaction speed and ability to shift perspectives, a necessary element for reaching the finish line in the game. Kongregate.com user and "Run 2" creator Joseph Cloutier offers two additional games in the series, including "Run" and "Run 3," on Kongregate.com. CoolMath-Games.com also offers the game for free.
