Fy_assault was built for a contest hosted on thewall.de in 2008. The original versions' filesize was 11MB and included two unneccessarily large easter egg areas, which is why I came back to polish the project in 2010.
So right after having finished the first version of aim_vicious in august, I removed the two pointless areas and completely reworked CT spawn. It used to be a blocky alleyway without exits and I figured the map reqired an actual entrance. Having finished the indoors part, I had to add scenery to the outside, which turned out to be easy since I had lots of ideas from having played GTA4 and Saints Row 2.
The day after that was done, I spent three more days tweaking light entities, adding graffiti, polishing up the main hall and placing weapons in a fun pattern (I think that's possible).
At this point, the map still had some gameplay issues. The two gates above the train tracks were almost closed, offering a great advantage to players in the main hall when being attacked by flankers. Cutting vents into the flanks walls and raising the gates finally put the map on the right path. Snipers now have a harder time camping and flanking is a much more viable option, which results in more exciting gameplay.
