Chapter 1: Upstream
After the prologue, we enter Chapter 1 of the main story: "Upstream".
At the start of this chapter, we appear on a carriage while being pursued by enemies. Once you regain control, hold down the right mouse button as enemies continuously shoot at you.
When you see a red glow around an enemy, press SHIFT.
When parallel to an enemy, lock onto them and launch your attack.
Enemies will also use blue-light attacks during this time, so remember to block.
When an enemy is low on health, press E to execute them.
After defeating two enemies, another enemy will board the carriage. Your special move should be ready by now; use it to instantly defeat him.
Next, a character named "Zhui Ming" will suddenly appear. You must fight him on the carriage. This battle is unwinnable for the enemy (you are guaranteed to win).
During the fight, hold down the right mouse button. When you see a blue flash, block to trigger a QTE. The enemy will enter a cutscene once their health is reduced to half. (If you run out of health, press R to use a potion. Potions replenish infinitely, so you'll never run out).
After watching a cutscene, our carriage falls off a cliff. Press F to wake up.
Upon waking up, you'll learn how to heal. Press R to heal; the number below the potion bottle indicates the remaining uses.
Press M to open the map.
Opening the map shows our approximate location and facing direction.
In the map interface, press E to open the quest list.
Golden swords indicate main quests, purple swords mark important side quests, and others are regular side quests.
Some quests can be tracked by clicking their icons (some exploration-based side quests must be discovered manually).
