It is designed to unzip to the correct directories if you unzip into the Half-Life directory.
darkness2.bsp, darkness2.txt, and Darkness 2 info.txt all go in Half-life/tfc/maps/
m_light1.wav, m_thund1.wav, m_thund2.wav, noaccess.wav, and all the cap wavs(theycap.wav, etc) go in Half-Life/tfc/sounds/M1/
That should work. If it doesn't, then you're hosed.
This is a straight forward Capture the Flag map. There are no elevators, and no ladders. There are no secrets.
The respawn room doors don't open for a few seconds to give people time to join.
After that, there are barriers over the exits to the bases that will fall after some time.. This should give engineers and defenders a few seconds to start getting set up. These barriers, however CAN BE DESTROYED EARLY! It takes a hell of a lot of firepower to do it, so a team that concentrates on a single barrier has a good chance to get a jump on a less organized team. There is a sixty second countdown before they fall.
There are two capture points per team. Each has different risks and rewards:
TEAM GETS: 3 points and a small health and armor bonus
PLAYER GETS: 1 frag.
TEAM GETS: 2 points. NO health or armor bonus.
PLAYER GETS: 6 frags. FULL health, armor, and ammo.
