The platinum trophy in Control isn’t difficult. However, you will have to spend 30 or more hours with the game. The most challenging part can be defeating a few tough bosses encountered in the side quests. However, you will be able to use cheats here. You can also go back to these fights after gaining new powers and weapons.
You don’t need to find 100% secrets to get the platinum trophy, although you still have to find the majority of them. Luckily, the game has two things that make this easier – you can do all side activities after you are finished with the main storyline, and none of the trophies can be missed. You can get all the trophies during a single playthrough. More information about the trophies/achievements in our trophy guide.
