Greetings, I'm a bit late but I have finally played PROJEKT WALRIDER and so far here are my thoughts as well as my first playthrough.

First of all I really like this map, love the atmosphere and the old school "World at War" vibes. I like the storyline and radios around the map and the ending caught us by surprise, very nice!
If I were to change anything I would add an outside area like a courtyard or something refreshing that changes the vibe while still maintaining the dark theme of the map. (especially since it's raining and something like a graveyard would be so cool.)

Here is our first playthrough: https://www.youtube.com/watch?v=2wCmmmvH3xQ
