Mach is a multiplayer Combat Flight game designed around modern day military aircraft from air forces all around the world. It features the F15, F16, F18, F22 and the EuroFighter. You can play as 2 different countries, Gibleum or Adanac. There are two game modes that a player can choose from, Combat and Racing.

The combat mode is a fast paced, interactive dogfight with players defending their respective home bases from hostile sorties. To help defend these areas are numerous surface-to-air missile sites or SAMS and shorter ranged Vulcan turrets. In order to achieve victory over the opposing team, players will need to knock out the deadly defenses and lay waste to the opposing teams base before the same happens to them.

The racing mode packs the punch of the fast paced combat mode, without the use of weapons to win. The player must rely on their skill to pilot the plane through tight turns, exhilarating twists and bone crushing G-forces to achieve victory over their opponents.
