The job.. Killer is Dead.
This game is a hyper stylized anime. I highly recommend using the Japanese voice over rather than the English.
You play as Mondo Zappa. A hired Killer or Executioner as far as I understand. I'm not entirely sure if this game was made by Suda51 or just inspired however its extremely in Suda51 style regardless. Additionally is not a successor to Killer7 to the best of my knowledge despite the obvious comparison.
The gameplay is tight and responsive. There were only occasional sections were I felt the game was being cheap. Mostly the sections where flying enemies were being spawned behind you. However overall anytime I was failing a mission. It felt like it was me being impatient with the game. There are leveling mechanics; Health bar, blood bar (special bar). As well as Carnage that can be spent on upgrading your abilities such as combos.
The story is told through chapters and each one completed opens up additional side missions. Which initially seems great. Who doesn't want more videogame to play. They just feel tacked on. Some are fun, some are even challenging. The game isn't long by any stretch but with underwhelming side missions, personally, I found my interest was waning near the end game. Though it does have a nice climatic ending, Its very well done. Almost made me go back and complete the side missions I had not already completed.
There are some technical issues
The game after setup is locked at 720p @ 31fps. Which is very strange. A simple .ini file edit can fix the fps to your refresh rate or desired one as well as the resolution. But beware, should you desire to complete the Gigolo side missions, you'll need to change the fps back to 31 (I believe its the max smooth rate line you need to edit) Otherwise the game will hard lock.
There is a lot of extra stuff despite the main campaign being about 7 hours. Desire to complete them all will vary from person to person.
