Exteel was a third-person shooter game published by NCsoft, a Korean game company, and was developed by NCsoft's E & G Studios. Players controlled giant vehicles called Mechanaughts ("mechs") and fought against the computer, or against other online players, in a variety of gameplay modes. The Mechanaughts were customizable. The game was free to download and play, but players could buy "NCcoins" with real money, through the NCcoin micropayment system.
