Shin Megami Tensei 3 Nocturne HD Remaster is a Japanese role-playing game in a post-apocalyptic setting. Compared to other JRPGs, this game stands out due to its rather gloomy surroundings and occult themes. Events take place in Tokyo. A high school student's trip to the hospital to see a sick teacher ends with the hero becoming half-demon and experiencing the apocalypse. And then he tries to survive in a changed world and figure out what happened. The main emphasis in gameplay is on exploring dungeons, solving puzzles, overcoming traps and fighting monsters. There is also trading, collecting loot and conversations with NPCs. Studying locations occurs in real time, as does moving around the global map. And when you encounter enemies in random encounters, turn-based combat begins. Fights are built on the need to look for vulnerabilities in opponents. Enemies are also capable of looking for weaknesses, which forces you to constantly change the composition of the party.

One of the features of the project is the ability to recruit demons into your squad and merge them to create more powerful creatures. The protagonist and these creatures can be upgraded. Shin Megami Tensei III Nocturne HD Remaster, as the name suggests, is a remaster. The original was released at the very beginning of the 2000s on sixth-generation consoles. Almost a couple of decades later, the developers made the project available to PC users. When porting the game to computers, they improved the models and backgrounds. The quality of music and sounds remains the same, but it is now possible to switch between Japanese and English voice acting. The creators added an achievement system. They also allowed gamers to save game progress anywhere (previously they could only save at checkpoints). The re-release has acquired additional types of difficulty. Some of them significantly reduce the barrier to entry.
