this pack consists of scripted based mods adding onto to l4ds core game-play and trying to make it as hard as possible while still sticking to the normal game AI and RNG are heavy in this collection, this is not for everyone YOU WILL DIE ALOT if you don't use teamwork, As you've seen in the official trailers, videos and comics from Valve there are some things that seem to be missing when playing the actual game, kinda stinks that alot of those features never made it into the official game, trust me i know i did. What this collection mostly consists are creations from the talented modding community that add these seen features and lore accurate scripts into the game, whether its EVER crossed your mind or not to have these ingame i welcome you to try these out for yourselves, the simplicity that made L4D great will never get old, but if your really itching to have some up-to-date features like other titles do then once again i encourage you to give this a try, of course everything is optional and they all work together, i would know if you've ever joined me whilst i host a local pub server i host one all the time, i love seeing peoples reactions to this, some mostly good than others (the typical online words used as insults) i get some good reactions for the most part, ive been asked if they can favorite this server but again its local not an actual server but ive had reoccurring players 2 of them join together alot and they compete on who's survived this server the most, its great fun, anyway enough self promo (BAN lol) so if you ever wanted to make L4D a more realsitic'ish game some see it to be? then AGAIN giver it a test drive you wont regret it, it does require time getting used to and believe me i havnt touched vanilla l4d in over 5 years, this game is 15 years old this November and that's crazy to think about its been 15 (16 L4D1) since this games release and we're still playing it, i love this damn game and its community, keep slaying them zombies (infected i know their not real zombies)
