As shocking as the opening scene of Hotline Miami 2 is, it is an obvious result of the game living in the shadow of its predecessor.
The first Hotline Miami (2012) was something wholefully unique and —sadly— the developers thought adding to that base alone would be enough for a sequel. More is less here, and Hotline Miami 2 not only ends up being less shocking and less thoughtful than the first game, but far more restricted in the gameplay department. The difficulty in Hotline Miami 2 is heightened in a way that the mechanics simply cannot sustain, meaning that cheap deaths are frequent. Expect to get killed by off-screen enemies a lot. The top-notch style is still there and the story has a few good moments, but as much as it tries to do more than its predecessor, it just ends up being too much. It might be a little disheartening, but the first game is enough as is.
