Will I Get Error And Purple If I Dont Have HL2?

I have tf2, ccs, l4d wil i get loads of errors and puple stuff because i dont have hl2?

CSS covers for most of it I believe. HL2 is still a very good idea to have. Plus, it’s pretty cheap, so I suggest getting it anyway since it’s one of the greatest games ever made. :3

Well, i want to buy it but i already have all the orange box for the 360 and have played them so the only reason for me to get them is if i will get errors and stuff.

When you get Garry’s Mod, you get HL2 content by default.
