A two-level solo map that is a great adventure. The first level is informational only, with a pretty good design idea. The second level is the main battleground for the story. You end up on a listening post and you have to activate.....well, I won't spoil it for you. The last terminal had a few problems for me, but other than that, this is a good map! Very well designed and I was impressed with the stair construction. Flow is good and lights are done well. For the authors first attempt not bad at all.
