After you stole all that guns with Ryder you have no award, but the money! That's not enough, I guess!
Now, after every completing Ryder's mission, Emmet's place will spawn a one more gun. There are tec9, smg and AK47 near the useless colt45, which you never grabed before.)
These is a real reason to visit Emmet lil' more often!
But warning, you'll can't delete this gun spawners after you'll save your game.
There are three cleo-files in archive, one for every weapon. Of course you can install only one of them or two.
I hope you like it.
Man, I try to do it for upgrading storyline, not just for fun.)
Ryder gave you only three missions with gun-stealing, that's the reason why I add only three more guns.) And all that guns you can see in the ghetto wars, that's second reason.)
