The 7-11 Map code and the Schick Map code are the same. The Schick code however comes with a theme that 7-11 doesn't. The Schick theme is called 'Killzone 3 The Hatch Theme'.
Please read better... I was talking the theme =\
7/11 has a snow based theme that looks like the MAG themes (odds are this was the code since the themes had copes)
the shick one you mentioned being free I explaiend above
