Following the tidbit of information for Final Fantasy VII Remake revealed at MAGIC 2017, director Tetsuya Nomura clarified some small details in an interview in Weekly Famitsu regarding the game's combat system.
“Battles are not command-based, they’re action-based. Regarding cover actions, there are places where they can be done on the map, but they are not required. Because it’s seamless, I showed that there can be actions in response to various scenes.
“The Guard Scorpion battle has map destruction and a great number of attacks that weren’t in the original, so it has become a significantly flashy battle. If you look closely, I think that you can see that there are a number of missiles are coming down.”
