In The Evil Within 2 you must beat the Shooting Gallery Chain Attack with 70,000 points for one of the locker key collectibles.
The Shooting Gallery becomes available at the start of chapter 4. To get the locker key you must score 70,000 points or more in Chain Attack Mode. You have to get as many tiles of the same color next to each other to make them explode in a chain combo. When they start to shake it means you'll get an hourglass reward from shooting them. This extends the time. To score 80,000 points it is vital that you always do high combos.
If you have tiles of another color blocking the connection you can shoot them. Compared to the Shooting Gallery on Very Hard this one is a bit easier.
