EA, is this because you do not know how to handle certain franchises, much like your even worse foreign cousin, Ubisoft? Or do you wish me to scoff at why you want us to challenge everything?
Anyway, in this game, which is very short at about 4 hours in length, Harry, Ron, and Hermione start their quest to find the Horcruxes, which allows Lord Voldemort to maintain his immortality. You control Harry Potter in a third-person over-the-shoulder camera and is a third person shooter with cover system. The camera can be very claustrophobic when taking cover during combat and is problematic when throwing exploding potions. There is a leveling system, but it is nearly pointless since there are almost no improvements made to Harry's spells. The healing items that the enemies drop are also mostly pointless since Harry has regenerating health.
Unlike the previous games, the game behaves more like a third-person shooter like that of Gears of War with the spells behaving more like guns than what they do in the books and films. For example, Expulso makes things explode in the book and films, yet in this game it acts more like a machine gun. The only ones that work like they're supposed to is Stupefy, Petrificus Totalus, and Confringo. There are in fact multiple spells to use to combat Death Eaters and other enemies in the game, but most spells have little to no use, except for Confringo (which destroys rocks) and Stupefy (your basic attack spell); however, Confringo would be useless if Harry jump since the rock barriers are small enough to do so. The game also tells you that you should use certain spells in certain situations which is false since as said, only a few of them are actually useful; for instance, the Four-Points spell is not really useful, making it hard to figure out where you're supposed to go. Harry Potter even constantly says the name of the spell you are using (likely to be Stupefy due to it being the only useful attack spell) throughout the entire game, which gets VERY annoying VERY quickly.
The combat itself is incredibly repetitive as you fight the same enemies over and over again with no variety. Even the boss battles are very hard such as the one with the locket Horcrux. The only way to win the fight is to start spamming Stupefy while moving back as far as possible to avoid the snakes and spiders. It even doesn't look like what it was in the movie. After a boss takes a certain number of hits, they make a ridiculous face with some of them looking downright funny.
There are stealth elements where you can use the Invisibility Cloak to get to certain areas. Harry can otherwise simply run past enemies most of the time to progress, making combat almost unnecessary as the enemies will never follow him. To hit someone with a spell while using the invisibility cloak, you have to get real close to them to guarantee the stun or else the enemies will start attacking you; speaking of the invisible cloak, putting it on in the final boss battle causes you to win the entire game almost instantly!
At times, Hermione or Ron will leave Harry behind which makes the game start side missions for him to complete. The side missions are forced and must be played in order to advance the game. Some of these missions happen at times that can clearly conflict with the narrative such as Harry going back into the Ministry of Magic after just escaping it. Another would be while in Grimulad Place, one of the encounters will involve Harry inside a cave trying to flee from a Hungarian Horntail. How Harry got there or why he’s there is never explained. When playing as Harry at least you can Apparate.
EA, seems like you've made some really good decisions, don't you.
