Tank Arena is a two-player game where each player is playing as a tank trying to destroy the other by shooting bullets. The controls are fairly simple; you have two players playing on opposite ends of the screen tapping the arrow keys to dodge bullets and position themselves at a better angle to try to shoot each other. The game is designed to promote more face-to-face interaction between users as opposed to just playing against each other through a phone screen. Go outside, meet new people by challenging them to a game, and have more direct interaction instead of just typing words and sending them to someone through a screen.
