Die Trying L4D2 by Captain Crusader & Valve & Nav Fix by 3ipKa*
The campaign kicks off with 4 survivors ready to take staying alive to the limit. Stuck near the bus depot after the bus they were driving crashed into a building, no longer able to drive, they are on foot. Travel your way through the streets and urban areas back to the outskirts of the city.
This one had L4D1 stringtables, no L4D2 weapons of any kind, NAV was bad, and and we had ported it back 2013. ALL FIXED. Not too bad of a campaign.
