that's what I thought but I was meaning the specifics, like does it reset the kills, or my stats.
both reset both in different ways; A hard reset (as mentioned before) essentially deletes all saved data, while a soft reset will maintain the previous data to make the game easier to progress, so in a sense it remeves the ammount of kills and stats in exchange for this or that to help the player progress faster, while maintining the "lifetime" ammount of each data set.
