Description

Updated 17 July 2009, fixed several issues & added a dynamic crosshair when using the keypads & lab buttons. Requires Episode Two.


This is the installer version. Hopefully it should fix an issue with the mod not showing up on steam games list at all.

Very late edit:
This mod was created by mbortolino, send your PM's to him about the mod.
I(DuckSauce) simply created this installer due to issues people had with the regular zip files.

Editted in now because Mod of the Year kicked in, who knows what people will flood here and get confused :P

200 words This is the installer version. Hopefully it should fix an issue with the mod not showing up on steam games list at all.

Thanks Ducksauce :D

I still wonder why it's so hard for people to open a .zip file :P

You open it with winrar or winzip and extract the files.

you don't have to, you can open with default windows, it's just easier with winzip :P (and you have to save it with windows)

Burn this guy!
The whole internet is full of .zippies

Well I love winrar :) it should be included with windows it is more popular than a .zip file

.rar extension has become popular thanks to warez. Since it allows archives to be split into pieces. Rapidshare uploadlimit fail! lol!

It is also simple when burning a large archive to a DVD, simply split the archive into 4.7gb parts ;)

Uhm, it doesn't go in either of those places. The mod folder should be at:

C:\Program Files\Steam\steamapps\sourcemods\

I finally got it to download, but nonetheless it was pretty frustrating. Hopefully Moddb can host the installer in the future.

wouldn't know, but it's the same updated version released yesterday, if you didn't download that one you may give this one a shot, I don't think it does fix anything related to Mr. Whirly though.

nope, I created it for the people that were having issues having it showing up on steam(it seems there are at least 2 possible sourcemods folders, the installer should automatically pick the right one for those people)

DuckSauce - I registered just so I could post here and thank you for this great mod. I thoroughly enjoyed it. I did find one place where I unintentionally bypassed one of your puzzles. Would you like me to post the information here, or how can I get in touch with you? I don't think this forum has a PM feature.

This forum does have a PM feature- view the member's profile and there is a send PM button there. And he only made the installer, he has nothing to do with the mod.
