So I was palying around with Source SDK and I was going to make a tset Mod for HL2: Decaying and I saw that the make a HL2 single player Mod was unlocked! I thought that you needed HL2 to make Half Life 2 singleplayer mods on Source SDK, but thanks to Ep2 the Mod may be worker on faster then I thought. So keep waiting! I want it to be one of the best Mods out there!
