Good time of a day, I'd like to ask, does sourcemod/metamod supports Blade Symphony's x64 version of a Windows/Linux servers?
If not, what should be done to have a sourcemod/metamod support for a Blade Symphony's x64 version of a Windows/Linux servers?

I assume, support comes to popular games more likely.

You can always try what happen installing MM:S and SM if happen at all.
HL2 engine games mostly are 32bit, this 64bit is new thing tough.
