This was, admittedly, my first map, and it shows. However, I'm told it's rather good for such a lack of experience (by my friends). The pillboxes were inspired by a childhood of laser tag. Everything else was more or less random, but the little raised bits that seem random are there to slow down careless players. Be careful ;)

Sorry about the pop-ups.
