this is a combination of HL: S enhanced and HL: S evolution
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.
Special thanks to everyone for reading this!
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.
