Call of Juarez: The Cartel

First chance you get to achieve this is in Chapter 1 by simply collecting 3 out of the 4 secret items. Keep in mind that each character (Ben, Kim & Eddie) have different locations for secret items but are usually around the same area. I have listed all secret items for all characters in Chapter 1. See below:

Ben McCall (Chapter 1)

• Item #1: right after you go down the rope it's on the right next to the van
• Item #2: right after the first one and you open the fenced door it's on the corner where the rope ends, on the left
• Item #3: after 2nd one you go up into a mansion, it's the house on the right the door is open.
• Item #4: after the above you have to plant 2 bombs, from the bomb on the right take the path on the left, it's on the corner on top of a crate

Eddie Guerra (Chapter 1)

• Item #1: after destroying both tents and reaching slopes. Before going down it's on the outer right corner
• Item #2: after going down the lift rope it's on the left on top of a big crate
• Item #3: it's close by to the first bomb planting behind it to the right, on top of a crate near the base of the house
• Item #4: it's inside the last house (where you plant 2 bombs)

Kim Evans (Chapter 1)

• Item #1: after destroying both tents and sliding down the slope, turn around it's on top of a crate
• Item #2: it's in area where you plant 2 bombs, the very first house on the right on the porch
• Item #3: same area as above, behind second bomb that you plant
