First of all I must thank everyone for helping me test the first version. The map was received much better than I had expected. The games were tense with a lot of back and forth.
I have incorporated many changes suggested by the players. The biggest changes include:
1. A revamped underground area resembling a road tunnel
2. A bigger and slightly raised cap point allowing for easier defense
3. A new corridor leading from spawn to the cap area
4. The fan now starts upon cap and changes direction depending on the leading team, making the map more symmetric (and thus fair, hopefully).
