Is There Any Way....

....To edit the settings in Warrock folders so you can get different weapons and stuff like that?

No, I don't think so because the bought weapons dinars and all other things like that are saved on the server in sql databases.

its server sided, yes
in sql, uhm.. no
sql is easy hackable

Of course it's saved in sql databases. When you escape all inputs it isn't easy hackable. In php there are functions like mysql_real_escape_string
