In fact, hacking and slashing with the machete can be so sick that it can actually begin to affect the player's mental health. Amacio told me that if you choose to kill your enemies in sadistic fashion, chopping away at their corpses, you may become temporarily mad, actually losing control of the character as he goes on a rampage. This unbalanced behavior can also impact how other people treat you in the game world.

"The more immoral stuff you do, the less people will be willing to help you, and they're gonna stop giving you malaria medication. So you yeah, you're gonna have a reputation where people are gonna see you coming in and they're like, 'It's that nutcase who kills people with machetes!' But if you don't do all those atrocities, yes, people will not be as afraid of you, and you will be stronger physically."

After getting back on my feet, it was time to get serious. Sneaking up behind a wall, I popped off a few shots with a silenced pistol, dropping a nearby guard. Picking up his AK-47, I noticed that it was significantly aged, rusty and degraded. Amancio noted that this is actually a dynamic feature--even enemy guns will break down based on time and use, becoming older and more prone to jamming.
