A new
Kickstarter project has been announced by a bunch of guys who used to be invovled with the rainbow 6 and Ghost Recon games. It is called (inexplicably)
Ground Branch and is still seeking funding, so anyone who misses those sorts of games may be intrested in helping them out.
At the moment, the list of features is small as they simply want to get the thing made but they are promising copious amounts of additional, free DLC later in to make it into a more complete game.
Some interesting posts and explanations by one of the main devs in
this RPS thread (he's called "jon C").
