They don't fart. Maybe that's just me from laughing so damn hard when I see a deer die. Part of the problem is that there is nothing evolutionary or revolutionary involved here. First off, I don't think its possible to give gamers a sequel in only a year. It may fly over in the sports camp, but it doesn't fly here.
Sequels are only sequels if they bring something substantial to the table.
Like in the original, they are useless and add nothing. Either increase their length tenfold or get rid of them. There is also no implementation of fatigue and injury factors. A unit with almost zero health should not run and fight like he had full health. Hopefully this can be addressed sometime in the near future.
