"HL²:SUBSTANCE is a single player campaign remix, developed for those HL² veterans who found the original game either too short or easy,and now ask for more. The levels contain now much more action and challenges - shortly, no one plays as before. The difficulty is higher and requires Nova Prospekt-like skills since the very start. You'll never fight alone, otherwise in the neverending battle that'll enrage on your screen you'd be in real trouble: keep your rebel/alien friends closer than ever. Gore is also maxed to satisfy your bloodlust."
