Maybe i am one of those who tried the older version of this campaign when it was only 2 maps and i just deleted that version i got so few minutes before i leave this review. I also remember that it was one of the very first custom campaigns i tried in L4D2 world as i was so excited to play through new environments other than those original ones that's why i mainly got my steam account for XD So i remember i left that review full of happiness on your incomplete campaign (2maps) thanking you for such effort because i do appreciate presenting those new environments through new maps and campaigns for L4D fans as it makes the game alive as if all these campaigns are connected in a way with different scenarios, skins, themes, scenes and more. Despite the fact i played that campaign only those 2 levels over a year ago, i was going through those 2 levels again so few days ago playing this complete campaign i downloaded months ago, retrieving all custom campaigns i remember i got one day, and i got to know where to go and when to end each of those 2 levels as if i played them yesterday. Of course it was a lovely terrifying experience to get into another 3 levels following those 2 levels i played and remembered to discover what was waiting for me on those 3 levels and it was completely fine for me. - I loved those warnings especially in map 2,3 & 4 about alarms in the market, houses and gates giving the player the option to go through them and start the alarm or find another safer way which i picked by the way XD due to another fact that i played it with Bots on Expert SP mode so i chose the safest ways to go through the campaign and make sure Bots were safe because it means i am also safe and protected. - The longest chapter was the 3rd and i found tons of supplies that bots had their HP almost filled plus a health kit they got besides bombs as it was really great and yes, it deserved a panic event like that to run in water to turn of the alarm. The only issue i got and i believe it's my own mistake as it was on map4 when i didn't know where to go and spent some minutes in that hole trying to jump to the other side, but the way was clearly shown through that building XD and still enough supplies. - The finale was so nice and it reminded me with Dead Air but it was inside a hall which was so clear. Maybe the radio lacked some voice over it to tell me anything, but it's fine. - Finished that campaign in 2 hrs & 5 minutes on Expert SP mode with only 1 Restart that was by mistake in map 2 by the highway when a tank kicked all of us XD . - I love this campaign and finally deleted the older version with only 2 maps to keep the most updated and only left complete version of that nice work. Yes, you came back and updated it or i just found the other version of that campaign after the incomplete one was deleted from website XD whatever... Thanks again!

Really enjoyable campaign. Only issue I encountered was the bots had a lot of trouble navigating on chapter 4, they teleport constantly and lag behind. Other than that though, really fun experience, huge maps with a lot of exploration, optional panic events, confusing but interesting and complex layouts and overall a lot of fun to play!
