One of the Greatest Games Ever! After all these years. it still Rocks and holds it's replay value. I will continue to play this game until the end. Just as i do Doom, Duke, Quake, HL.. It truly is one of the greats. and i think most new games lack severely in all levels of development compared to a game like this. Valve Produced a Masterpiece. over 700 ways to chop up a zombie! but i'm old school. i like fast pace action, in your face, where hand eye coordination matters. Not pay to win micro-transactions or the new fad wave game for streamers to hop to for 3 months. This is a game that is for Life and that will last the Test of Time. Promise
