I started playing with the wonderful 3rd part and will compare the new part with it.
The developers had a good idea to replace the scenery of the island with mountain valleys. The game has become more multi-level and, accordingly, more interesting. We also improved interaction with animals + added a helicopter.
As a result, the gameplay part has become better, but the atmosphere of the civil war and the plot component leave much to be desired. I lack empathy for the main characters, and I also lack the charisma of the villain.
As a result, I will give the game: 8.6 / 10
