Half-Life 2: Substance re-choreographs the original single player campaign, John Woo style. Intensive new action and higher challenges makes it the best choice for HL2 veterans who found the "vanilla" version either too short or easy. Squad tactics and accuracy are actually required now. A whole new set of weaponry is also available as well as an advanced friendly-fire system, a skin pack and a sound add-on to further personalize your second visit to City 17. Welcome to the real Substance, what action is made of!
