The omnipotent air-raid siren wails throughout the nuclear test site. You stop in your tracks, your mind focused on this divine voice from the heavens. For a few seconds, the hell that is Half-Life 2 Deathmatch ceases to be - no bullets zip past your naked ear, no rockets blast forth from oblivion, and there's no crazy G-man about to drill a crowbar through your skull. Each individual combatant looks to the sky, knowing that in a few moments, that infamous nuke will burst forth from the cloudless void, obliterating everything topside. [br] [br] Ka-thunk. A crossbow bolt breaks the serenity, lodging itself in your left shoulder. The Barney opposite glances at you briefly, before opening fire with an MP5, screaming taunts. He's silenced by a stray rocket which blows you off your feet, like cold water to a drowsy face. Heaving yourself to your feet, the word "run" comes to mind. So you do. But as you’re panting through the narrow tunnel leading to the sacred bunker, a scientist leaps out from behind, screaming something about ridiculous ties as he pulls the trigger of his giant energy weapon and blasts the left side of your body into smithereens. Replying with a swift magnum bullet to the head, you're left to hobble forward; into the daylight; into the open battlefield lying before the Holy Grail. [br] [br] The bunker door is lowering, but you’re going to make it. You have to make it. Mr. Rocket says otherwise, however – or more accurately – he echoes "Boom" while stealing all but one of your health points. Whipping around, you see your old scientist friend wielding a bazooka, and he looks pissed. You have a choice – dive through the closing bunker doors, to safety – or teach this lab rat the meaning of pain? [br] [br] Ooops, too late. [br] Bang. [br]You die. [br] [br][br][br]HLDM is great. Do yourself a favour and pre-order Half-Life 2 Episode one, just so you can play Crossfire with ragdolls, explosions and physics.
