[+] As stated by others it's very long
[+] Takes elements from official L4D maps and fits them in perfectly
[+] No buggy navs
[+] Good texture placements
[+] Great level design
[+] Challenging
[+] Not too much ammo and health for extra challenge
[+] Many extra places to go into
[-] Bots seem a bit bugged at finale
[-] Some places are confusing as to were to go
Overall definitely worth a download! Possibly one of the best custom campaigns yet!
Great custom campaign!
