Iron Grip: The Oppression is a Total Conversion Modification for Half-Life 2. The mod includes gameplay never seen before, providing real urban guerilla-warfare by a unique combination of elements taken from both first-person-shooters and real-time-strategy games.
A player can choose one of two sides in this game - Rahmos or Resistance. The Rahmos side is a real-time-strategy game played by, initially, one person. The Resistance side is represented by numerous players who play a first-person-shooter.
