Hostile Intent is a Half-Life modification which uses a flexible objective system that provides each team with specific goals to accomplish in order to complete their mission. Players take on the role of either a special forces operative ("Nato") or a fighter ("Tango"), and are tasked with certain mission objectives they need to accomplish within a time limit (one round of play) in order to win. These missions can take place in virtually any real-world location, from urban city streets to dense tropical environments to sandy deserts. The number of possible scenarios and mission objectives is similarly infinite. Players could be disabling radio communications of an enemy, defending a building they’ve secured until support arrives, defusing bombs, and much more.
