I have an irrational hatred of knockoffs. The original map is great, but that's not your own work, now, is it?
Under Veil of Night is a solo map based off of Envy's map "Citadel". I retextured it in visualmode.lua to make it a nighttime version. Don't complain about how you can't see where you're going at times, because that's the point. There are certain bright points for reference.
