After playing trough on normal two or three times, I came to make this review. The maps were all really well-designed, very "japanese" on all parts. Also, they all had cool places to explore and to gather items. Talking about items, they were plenty and well distributed. It was really fun to play through and to just look at the details and feel the atmosphere. No NAV errors, with both zombies and bots. Only errors were some props that disappeared, only having a big red "ERROR" in them. That aside, perfect job.
Also, might I ask how long you took to make this map?
