I played 700 hours in the game, completed all the additional missions, found all the paints, drawings, Easter eggs. The game has good replayability, although there is no choice, but it is interesting to run around the city, village, fields, slums in search of Easter eggs, small details that the developer left. It's better to go through this game alone, and only then play with friends. There are many players in multiplayer who, using programs that made an endless grappling hook with the effects of freezing, poison, fire, a crossbow with 60k damage, swords with 24k damage.
There is an interesting night hunter mode, when you burst into the game as a mutant while people are going through the story or wandering around the map.
They add a lot of content to the game, fix bugs and, in principle, support the game well after so many years.
