For me it came between WarrenM, YayitsM4tt, or Foufoune_Rose.
WarrenM created a great sense of atmosphere with lighting and learned 3dsMax very quickly. He created good looking props and spread a fair amount of detail, evenly, around the level. As far as being a playable level, however, it seems to have its limits-- with the most potential as a story mode level.
YayitsM4tt put an interesting spin on the Crysis engine by putting together a fun and spooky looking level. Again, the lack of height variation leaves me to believe this level would have the most potential in story mode. I especially liked the WoLD light trick in this.
Foufoune_Rose's level looks as if it were straight out of a nightmare. The usage of height variation means it could be used in either story mode or multiplayer. Some areas could have been more detailed, but for the time frame the presentation is totally acceptable.
In the end I voted for YayitsM4tt and yes, I had to flip a coin to decide . Congrats to everyone who completed their levels and good work!
