Challenging in Expert mode

This is a very good map, finished the whole campaign in Expert (of course I died few times lmao) XD

You just need to utilize those gascans and pipebombs on the map 6 when repairing the generator :^)
(Keep your vomit jar and adrenaline shot if you loot one before escaping, this helps a lot.)
You might probably want to bring a melee since horde spawns very fast. ^^

I'd say this is an 11/10 map because I like long maps :D
