Query about sport model and suggestion

I'm not sure concerning the content material of the three variations of Sniper Ghost Warrior 2. It appears they solely have weapon skins; I don't know in the event that they have an effect on gameplay, however I'm questioning if it's price getting the one which's on sale or ready for the bottom model. Do the weapon packs considerably have an effect on the sport? And now about Mortal Shell, I'm not sure if it's price shopping for. I noticed some movies about it and located it fascinating, however I assumed the motion was a bit unusual.
