Insurgency: Modern Infantry Combat is a very interesting modern military shooter. It's the only one I know of (Counter-Strike doesn't count) that's a mod. So put down them Calls of Duty and let's play it! 1PM PST, Sunday, June 19 2011.
"Insurgency (INS) is a total conversion based on Valve Software's Source Engine. Insurgency immerses you into an intense multiplayer combat experience. Set on the modern battlefields, Insurgency simulates modern infantry combat that doesn't just encourage the use of teamwork and tactics, but makes it a requirement of survival. The current Operational Theatre lets you go head to head with guerrillas, insurgents and resistance fighters in Iraq and Afghanistan; placing you in the center of current conflicts like no other first-person-shooter. Immersive suppresion fire and damage effects, 1-shot-1 kill dynamics, and accurate weaponry ensure a pace and a dramatic tension that few other games can match."
