Basically all SoHL versions are ready for download versions:
1.0
1.1
1.2 (now has source code)
1.4
1.5
1.6 (still need to find source code )
1.7
1.8 (now has source code )
All versions work so don't complain if a version doesn't have something, because either its too old or you have to code it yourself.
I checked something in my PC and found the SoHL 1.2 code.aaron_da_killa gave it to me last year.And when did SoHL 1.8 came out?Let me just post it in moddb. Gamefront.com
Thanks tnk_x5000 for the link now v1.2 has source code which i couldn't find.
