The Witcher 4: 10 Ways To Blow Wild Hunt Out Of The Water
3. Incorporate The Environment Into Combat
Speaking of expanding combat without changing it too much, for the most part your surroundings - despite looking stunning - didn't play any part in fighting enemies.
Yes, you could duck behind a rock or tree to avoid some wayward arrows or a fireball, but there were no mechanics or animations tied into taking stock of the land. To that end, jump and drop-attacks should be a given (they work a treat after kiting enemies in Breath of the Wild and Horizon Zero Dawn), but let's also have larger enemies like Fiends be able to get stuck in thickets of trees when charging, or otherwise slowed when drawn into expanses of mud.
Fighting indoors should also come with its own set of restrictions and tactical considerations, letting you goad enemies into getting caught on furniture, or perhaps fleeing from room to room, if it's an apparition we're talking about.
Now that CDPR have the basics of combat down, it's just a case of expanding in ways that feel natural, rather than upending the overall feel entirely.
