Go southeast from the start of the map. You must take out a couple bandits in a small gathering of huts, but keep to the south east. You will find a red weapons crate up on a ledge. This was intended to be obtained once you looped around the map and were on your way out. However, there is a way to reach the ledge. On the right side is a cabinet to open. Jump on top and locate a post along the fence. Jump to the post. From here you can jump onto the ledge with the red weapons crate. Then, continue southeast. You will encounter a hut with two bandits. Continue southeast along the water's edge. Once you pass a large boulder, you will see a ship. There is another red weapons crate on the ship. You can repeat this by going back to the save point at the start of the map, exiting once, and restarting by loading your character again. The weapons crates will have respawned.
