Gmod "Blood" question.

How does it seem that everyone has Tf2, or left 4 dead blood but me? Is there a way you like activate it, or something?

I don’t really care about what blood is used.

Well I just believe the blood used in those two games are more realistic.

How?HL2 blood is much more realistic.

Have you ever played Left 4 dead? And anyways when I do play GMOD, when I shoot someone little specs go everywhere, and it looks aweful.
