Insurgency Website now features a new beta version 2.1 of this Half-Life 2 modification centered around modern infantry combat (thanks Gamer's Hell). Here's how the project is described: "Insurgency (INS) is a total conversion mod for Valve Software's Half-Life 2, powered by the Source Engine. INS immerses the player in an intense online combat experience. Set on the modern battlefields, Insurgency simulates infantry combat that encourages the use of teamwork and tactics to close with and destroy the enemy."
