If you want 4044 specifically you can download this:
https://drive.google.com/file/d/1UFblKKMuJDfPKe7SwH6JBPwE4_yWi2Hu/view
Or check out the Source Unpack:
download the GCFs from here:
Download the Source SDK 2006 and copy all of that over it and run hl2.exe
Alternatively you can link me your steam account, I’ll verify that you own HL2 and give you a link to an earlier 2707 build of HL2, premade.
