Nice campaign that is well balanced. Especially the 4th level with the moving train across the bridge was very nice. The finale is a bit difficult but enjoyable nevertheless.

I remember this one from several years ago, and after revisiting it with L4D2, all of the polish and pacing still holds up. The finale is a longer one and a bit tougher than the norm, in that you have to cover a lot of ground, but the items make it reasonable and it gives the campaign a different feel. Add this to your regular rotation if you haven't tried it yet - it is a gem.

Well built and adequately balanced, with possibly the exception of constant mini-hordes and periodically double Special spam. The finale is tough, but the supplies are plentiful. Those small Survivor conversation also add up to the atmosphere.

The maps were nicely designed,no errors,glitches or pink/black areas. The atmosphere was good with the intro/outro. There seemed to be a balanced supply of weapons/ammo/throwables on normal realism when I played. Finale was interesting though the entire campaign was pretty challenging with lots of specials to fight with hordes. Only cons were the bots seemed to get stuck at certain places,especially ladders. Aside from that I'll be keeping this in my addons folder.
