The hypixel map is Available here: http://hypixel.net/threads/zombie-apocalypse-minecraft-adventure-map.662/
but the texture pack link won't work in newer minecraft versions. 1.7 - so I eventually found this link. detailed-the-end-is-extremely-nigh-revolution-official-continuation .
This pack is compatible with the new minecraft resource-pack mechanism. The pack however still looks broken/fails to load after you drop it into your resources folder... The catch is that you need to unpack the correct folder into your resource pack folder, dropping the zip does nothing, that's because the zip has 2 packs in it, select the non OSx folder inside the zip and copy just the folder into your resource folder.
It takes a while to load the map. I ran this map on my vanilla 1.7.6 downloaded server - it complains a lot about corruption and so on, something I often see (but never this badly) whenever I download a map anyway. This means that in transitions (when the map teleports you to the next level or area) you will disconnect and need to re-join. Be patient and wait a few seconds before you re-join and you will be fine.
We completed it with three players which probably means we found more items and drops than normal and also got stuck a bit more than normal because there are a few doors that you cannot go back through although that never caught us. It is pretty hectic, and a lot of run, and has multiple endings - so we will definitely play it through again.
