This is not the first time I played the campaign, but I wanted to leave my conclusion of thoughts.

I like it! This has become one of my favorite custom campaigns to go through when looking for something relaxing.

- Weapons are generous and righteously scattered all over the map. There's not a moment where I and the bots ran out of ammo. Throwables, melees, and medkits are available at the author's own little checkpoints.
This prevents players from having to scavenge further outside of the intended escape route just to restock on ammo.

- Players are rewarded for finding camping spots with ammo piles in places the author planned in advance to be the most difficult.

- Sporadic spawn rates of Tanks and Witches. It's not too many, nor too few. You'll encounter 1-2 of both or either in the same level.

- Special horde events such as activating an elevator or tripping an alarm doesn't spawn too many zombies. Much fewer than the official campaigns itself. On Advanced and Normal difficulty, I never found it frustrating to be surrounded by zombies in normally-sized rooms.

- Super easy finale. This is a huge advantage after the tedious crawl through the levels on higher difficulties as the Tanks might spawn ... once. I believe only one tank spawned throughout the whole finale.

- Aesthetic - Really well done. I didn't look at the description prior to installing the campaign and mistook it to be an unfinished Valve campaign. It looks official but you can tell the author has taken their time to putting every detail to make sure the map is playable.

The offices and the cityscape are small but easily missed details to appreciate. The skybox is a better improvement than No Mercy's rooftop finale. I think my favorite aspect was the Union Tech building itself.

- The finale was a bit longer than the usual. I've seen other users report that it was "too easy," however, I believe it's a longer waiting time between the finale starting and the rescue itself. I noticed only one Tank spawned so I used the Admin System to call the rescue early to finish the campaign.

- If you want a bigger challenge, you could install mods that accelerates Special and Common Infected spawn rates. More smarter bot AI for both survivor bots and Special Infected could make it more fun.

- Totally play on Versus mode and have a buddy to finish the campaign with. It's more fun that way!

- If you want a similar campaign in terms size and aesthetic, give Infected City and Downtown Dine a try.
