71 edited levels: the whole HL2 game! Older levels have been revisited for more challenge and performance. Welcome to the real Substance, what the action is made of!

Squad tactics and accuracy are actually required now: see what the G-Man meant by "a battle you have no chance of winning" (because you didn't submit, then, right?)! A whole new set of weaponry is also available as well as an advanced friendly-fire system,a skinpack and a sound addon to further personalize your second visit to City 17. 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.
