This map is a JUMP map for hunter practice.
The hunter must jump his way through the various obstacles to get to the survivor suspended in a container from a crane and then kill him. If you step on the cockpit of the crane the container will be dropped.
This map can only be played using the hunter, so you should use the M key to switch to the infected and then use the console kill command to suicide until you spawn as a hunter.

The map is extremely difficult, but if you are able to clear it, I think you'll see a massive improvement in your hunter skills ;)

I'm not a native english speaker and sometimes my explanations are not clear, so I have posted a video of the map at youtube. The sound on the video is loud so lower your volume (the hunter screams everytime he jumps).

Again, because I don't understand English very well, I may not be able to reply to all comments or questions clearly, or at all.

5/15 update

I updated it.
It is revised the bug that I cannot change by the infectee side

2/4 update

I got a lot of feedback from the player who played in speedrun.
I prevented a place to have on the cause by a short cut in it.
Because I did not understand how the method that was over by 0:18 went, I was not able to revise it.
I made timeattackmode with speedrun for the player who played.
I make a stopwatch, and a timer works when in first startbox.
A measurement can play this timer until 10 minutes.
However, it is not a precision timer.

I think that there is the place that can still do wrong, but revise it if I have you send feedback.

How to play maps

You download a map and put a .bsp file in
Program Files\Steam\steamapps\common\left 4 dead\left4dead\maps

And a game begins when I input it with "map l4d_vs_hunter_city_b1" from a console.
If you are a survivor, I push the M key, and please become an infectee.
