If you are reading this you are either; a nagger, or you are someone who is interested in making a modification or game... Well a game might be over the top since I do not own a gaming studio but modifications, I can help you with that.
A Modification is a people-made version of a game using their own creativity and designs. Of course modifications aren't supposed to be as great as the original game.
For example;
Call Of Duty 4
+
Zombie Mod for COD4
=
A Modification.
If you still do not understand this then email me at (armyfan5000@yahoo.com
I will occasionally upload songs that might be used in future modifications.
