"Great standard for indoor campaign."

I admit that there are some outdoor areas, but for most of the campaign, you are inside somewhere, so... We open with the most unique start to a campaign ever by being isolated by ourselves at low health with only a pistol to defend ourselves. Common infected, which are usually underestimated by everyone, suddenly became very scary. Players are forced to play more slowly and stealthily, even on lower difficulty settings. The vulnerability that the player feels helps make getting the second pistol or magnum truly feel like a meaningful upgrade.

The rest of the map feels like an abandoned office with some secret inside it. Sometimes, you can get lost, but not so lost that it becomes unbearable. There is various cool stuff like slow motion, funny jokes, and even a section where you have to build some barricades like a certain mutation. Although I have seen campaigns with better indoor, I think this one set a good standard on how to make one interesting. Most maps have terrible inside areas, so this is actually noteworthy.
