Information needed

Can someone please explain the differences between the rising storm game options available on steam?


eg. Rising Storm
Rising Storm digital deluxe
Rising Storm digital deluxe upgrade


And in the tripwire bundle...Red Orchestra 2 with Rising Storm, and Rising storm game of the year edition...


Trying to figure out what to purchase but I can't find descriptions anywhere...


Which of these games if any, work on LAN?


Thanks -
