Is Alpha 0.52 engine considered GoldSrc?
well you can play alpha maps in retail by putting them in your valve maps directory and yeah there are some bugs so i guess?
Did you actually manage to make a map in the 0.52 engine of is this ported from modern Goldsrc?
Yep this is all specifically made for 0.52 engine albeit with modified VHLT compilers that output bsp compatible with Alpha
Interesting! I've never heard of people using the alpha engine to make maps so this seems really cool to me!
