Another Day at the Office image - Black Operations mod for Half-Life 2

Fight your way through the abandoned, war torn streets of New Metro City as Black Ops agent Declan Walker. Use your influence as a military operative to call in support from the skies, use advanced vision enhancing technology to silently stalk your enemies, and take down nearby hostiles using a new melee counter system. You are no longer the hunted in Black Ops. You are the Hunter, and this city is your preserve.
