"Take to the streets for intense close quarters combat, where a team's survival depends upon securing crucial strongholds and destroying enemy supply in this multiplayer and cooperative Source Engine based experience. The follow-up game to the award-winning Source mod, Insurgency is highly competitive and unforgivingly lethal, striking a balance between one-life gameplay and prolonged action."
A really interesting, fun and definitely hardcore shooter. If you're interested I'd recommend giving it a spin.
