This campaign has a lot of potential, but it's really far from done. Played with a friend and two bots on realism advanced. (v1.45) with barely any mods. It was crashing after a certain cutscene on the first chapter. Must be tied to texture overhaul or graphic mods. First of all, the map design is really good, I rarely ever saw any texture or asset used from the original game. Liked the custom ambient soundtracks, custom voices, custom texts, custom credits, cutscenes, the dark weather style, hidden enemies, hidden items, traps were also appreciated. Item placements and events are good, the hordes feel balanced. Even on a certain part zombies keep disappearing and the horde is stopped so the team won't get sandwiched in with them with 2 tanks, clever. But from here, things are changing: The invisible walls and a "bit difficult": I understand that unfinished parts need to be blocked away from the players, but some are Not. I died more times instantly from entering places where i shouldn't be than from the campaigns "difficulty". Found a crack between walls? Don't enter it, you most likely gonna die. On the 5.th map, leaving the saferoom you can go outside on the left (which is not show on the video) or go straight from the highway (which is also not shown on the video). Both are basicly places of instant fatality. Some changes I hope for: The whole thing is very linear, not what i expected. Not many places to explore, it's mostly about going a little...event, taking more steps...event, and then you reached the saferoom. Details: currently some props have no collision and/or they are transparent. For example, the finale event, almost fell to my death while going through a fence and a pile of bags. Also a lot of places still need filling up with props, cause currently it feels too empty. The tanks health feel modified, they have a lot more than they should, plus the chapter with mudman only is a bit too much. All in all I still recommend everyone to try it, this campaign has a bright future behind it.
