I believe the best aspect is its variety during gameplay. There are different scenarios where you have to approach different situations, such as fights against mutants, against humans, and moments where stealth is required, and so on. Another good point is that the maps are small, so that you won't get bored. In other words, it’s a game that keeps your interest from start to the end. On harder it’s quite challenging, you’ll need to save resources in order to survive.
In this "remake" version the game was censored (they removed several Soviet symbols) and still has bugs that prevent you from completing missions. I dropped the game.
