NecroVisioN is interesting garbage. Meaning that it is *so* bad to play, but also kind of fun. Like an entertaining B-movie. Guns are as effective as a hushed whisper, screen gets smeared in vaseline each time you get hit, in other words, constantly, movement is awkward and getting stuck is a rule instead of exception etc. The list is endless.
But at the same time, the game is hilarious. The script was written by a 13-year-old edgelord, the action hero main character sounds like he was voiced my an assistant math teacher and a "Vampire shotgun" is a concept that exists in this game. Some of the enemy design and levels are actually, well maybe not good, but interesting. And combo based gameplay is cool in theory, except the execution is abysmal.
It is a fun game to play while having a beer or eight. But I can't recommend it, because the game kept crashing at a certain point, preventing me progressing and thus finishing the game. Your experience might be different, but best wait for a deep, deep sale.
