Yes ,I am going to make a mod of cod4. I am not a professional level designer or programmer, As a noob there must be full of difficult ,But that's not a big deal.The most important is that i enjoy it.
Makeing a new game is a dream which is impossible for me,But modding can be.
Cod4 supply a set of tools ,that allow me to mod most parts of the game
What i should do is just improve my knowledge and skills. Maybe it was out of time.I mod just for me for my dream.
I do need any advice about that,if you have sometings just talk to me
