User blog:Dorgles/Human Revolution Pre-Order content released as DLC on Steam

Steam players of Deus Ex: Human Revolution have been wondering when they could get their hands on the Silenced Sniper Rifle, Double-barrel shotgun, Grenade Launcher, Remote Explosives, the You Scratch My Back, I'll Scratch Yours quest, and the additional 10,000 Credits from the Human Revolution Pre-order packs. They are available as of today, with the Explosive mission pack costing $2.99 USD, the Tactical Pack costing $1.99, or both can be bought for $3.99.
