Also unaltered are the gameplay elements.
Island Thunder adds 8 new missions and a handful of multiplayer maps to the mix, but besides that, there isn't much else. Thankfully, though, the plot is fresh and does the name of Tom Clancy well. Set four years in the future, after the death of Fidel Castro, you and the Ghosts are sent to Cuba in order to keep Democracy alive, and this means killing as many radical guerillas as possible.
The levels this time around are good, but they are basically the same experiences played over again. And while this isn't bad, as Ghost Recon had some awesome combat encounters, if you didn't like what you got in the first game, there will be nothing here that's going to change your mind.
