This map is made by "Alec"
It's a nice foggy map, good atmosphere with a few small buildings, some underground tunnels and a working (human/zombie ?) cannon.To open certain doors you need to find the power button.
Your map needs some more optimization, because it's very laggy when everybody is runnig outside.
Try this link on how to optimize your map better.Further more when there are alot of humans together on a wall it's to hard for the zombie's to get then even by using the cannon i find it very hard.
I found something that could have been causing the horrible framerates. apparently vis is a much dumber program than I gave it credit for. I fixed it so that the map will now be divided better and counterstrike won't be trying to draw the entire map every time you're outside. It will probably still get clunky at the higher points (cliff, wall, roof) but i'm not sure I can do anything about that.
someone suggested that the fog might also be causing lag. I kind of like the fog, and I don't know how much it costs in the map so I just compiled two versions. Since I don't have a zombie server I'll leave the determining to you. zm_holdout_b4f has fog and zm_holdout_b4 doesn't. they're both in the zip file. Try them out and let me know which works best...
Now your fast Alec i personal like the foggy version.
OP = updated
Well i played b4f on our server but if people are close together it still gets laggy sometimes but less laggy than b3, haven't tested without the fog yet.
