What will happen if we get mixing two cool games in one? The HL1 Inside HL2 mod will born. In this mod you will fight with old enemies from Half-Life 1 on Half-Life 2 levels using Half-Life 1 and Half-Life 2 weapons and get friendship with old known allies. Some monsters and non player characters are coded, but some are replaced by the model. Also, except for the Half-Life 1 and Half-Life 2 weapons, you can see Alyx Gun, Annabelle and Stunstick weapons coded for this mod.
