An interesting question, with hopefully interesting results.
When the map came out, I personally saw very mixed results about the map itself. Many said it was an easy map for high rounds, some said it was very confusing to navigate, and very little actually criticized it in whole. Now that I (an Xbox player) got my hands on it and got a general feel for it while still in the honeymoon stage, I'm curious to see what the community thinks of it all-together.
To be blunt, I love it. Imagine Shangri-la, Shi No Numa, and Resolution 1295 (Buried) had a baby. Zetsubou no Shima would be the ideal offspring. Why? Simple.
Very wide map with many different levels to it (Buried).
Hidden corridors and confusing hallways that making navigating around an adventure (Buried).
Enriching atmosphere with some to little eyesight for what's in front of your pathwise (Shangri-la).
Creep factor of the environment and the zombie pathing (Shi No Numa).
Multi-levels tucked away at the back of the map with many close-encounter rooms (Shangri-la).
Traps that allow you to tuck in a certain area for a while and train efficiently where you're at (Shi No Numa).
Mythology up the wahzoo (Shangri-la)!
Honestly, this is the ideal kind of map. Great murky atmosphere for zombies, sense of dread coming around each corner, the feeling of being lost because of multiple corridors, scattered arsenal and perk machines to make surviving early on rather challenging, and the ability to actually CHOOSE MORE THAN 1/2 AREAS TO SURVIVE IN COMPLETELY.
What do y'all think? Would you call this the "perfect" orientation for a map?
