• Secure the rare Almir’s Toast.

What is the Almir's Toast?

You find it in random present cases, I guess. I opened one and Almir's Toast was inside. Careful, though. It makes you move super super SUPER slow while carrying it.

I found it on normal difficulty. Be sure to stay at the lumber mill's ziplines so you can move to the helicopter as soon as you hear Bane tell you where it is going to land. (Otherwise the chopper will be gone before you get there)
