I think this is a decent map. Nothing special about it, and its very generic in the looks. Map 2 has nav errors which make this map unplayable in versus game mode.

Playing to the final, & it's a great campaign. The bot navigation is fine, & the supplies are enough. The instructions along with the highlighted objects are clear as well. The only problems I found were the common infected spawn point on map 1 & map 2. I don't know if it's intentional or not, but map 1 seemed too quiet when I played. Usually, there's incoming attack every few minutes, but when I played on map 1, there were very few incoming attacks/ panic events. Even when I opened the rolling door after pressing the switch, only few zombies & special infected were coming. Map 2 was similar as well. Maybe those common infected spawn points on those maps during panic event need to be fixed later. . On map 4, it's a little confusing for awhile when survivors have to run after opening a gate near harbor. I stayed & defended for few minutes there as I found a dead end because there's no guide arrow anymore. Later I found out after some special infected were stuck behind the blockade, only running left and right & looking survivors from there. So I took a speculation & found the path. . & the finale is cool. It's rare to defend until the rescue team arrives while enjoying scenery of a shallow river near the lighthouse. . So, in overalls, it's a nice campaign to enjoy. Only few fixes are needed.
