Hi this is gonna sound lame but i have no idea where to find HAMMER (the level editor) i have been lookin for it and cant find it. i have the CD version of HL2 that i bought in a store....not over steam. thanks in advance. and is there somewhere i can get a model viewer?....to see models without having to replace a model in the game....but view it from my desktop?....thanks
Steam > Play games > under 'tools' > Source SDK Contains hammer, model viewer etc.. but you have to download it. mabey 100-200mb.
