Clutching the precious Code Fragments, you climb out of the cursed desert temple and head to Quarryvale for the next clue and some rest. It seems Satoshi has hidden his next set of puzzles in the mountains. It looks like you are not alone though, and bad news strikes.
This is the fourth episode of Satoshi's Treasure. Playing the previous three episodes first is highly recommended.
Satoshi's Treasure is a multi-episode adventure map focusing on story, puzzles, and large-ish builds. Like typical adventure maps, you go around exploring places, killing monsters, collecting items, talking to NPCs, and unlocking the next part of the story. In addition there is a CTMish aspect where solving puzzles gives you Code Fragments. If you have all of the correct Code Fragments in the last episode then you can try to claim Satoshi's Treasure.
Episode 4 is moderately difficult and can be completed in approximately 1.5 - 2.5 hours. Potentially longer if you get stumped by a puzzle.
There are five episodes in total.
