another stupid half life question

i've heard that you can play the original half life as opposing force's adrian shephard, but i can't quite find info on how to do this? anybody know? thanx guys.

/me waits for answer
...and post hell.

wtf

no

You mean... play opposing force?

According to this you can, but it does not tell how.

perhaps then, you can /map to an hl map while playing opposing force?

yes, you can do that with most hl mods in fact I believe (cs being an exception)
