Two types of game modes, story mode and extra mode, are available
There is a status called infection value, and it rises when you receive H acts.
Once infected, it rises over time and affects stamina consumption. When the maximum value is reached, the game is over.
There are restrictions on the availability of ammunition, and the game mode is tense.
Easy difficulty is also available so that even those who are not good at shooting and action can clear it.
With Easy, there is no penalty for infection, so the game will not be over. You can get a lot of ammunition and the enemy's physical strength will be low,
so I think you can clear it even if you are violated by Guchogucho.
