Honestly, this mod is not made by me and it is made by someone from youtube or I don't know who is it, but one thing is the credits go to that person.

As I told you, this is a combination of HL: S enhanced and HL: S evolution. So, all the credits go to the developer of those mod. I made nothing, but just posted it on modDB.

For the release date, I just don't know it exactly so, I just posted the date that the developer or publisher post the video about this mod on youtube.

Actually, that video is a official trailer of HL: S ultimate definition. I posted the video here so, everyone can watch it now.

You can download it here directly in one file in :
or with parts here in mediafire:

Some credits goes to Stefen Wimmreuter for his awesome bullsquid and houndeye models, and boris for ENB series. Sorry that I forgot to mention these before. Forgive Me.

WAIT! I've found the answer to life (Installation Instructions).
1) Download the mod. Also, you need Winrar for this.
2) Open Steam
3) Right click on HL: S, click on properties. Go to local files and click browse local content.
4) Click on hl1/hl1_HD
5) Put the mod on your desktop to make this easier.
6) Right click on it a click extract here.
7) Open the ZIP file that was just extracted.
8) Click on hl1 when inside.
9) Drag everything inside into the hl1/hl1_HD.
10) It will ask you if you want to replace all the stuff, just click yes.
11) Your welcome!
