A Nitro Splicer appears on the balcony above the Circus of Values vending machine. Have Telekinesis equipped and use it catch one of the grenades the Nitro Splicer throws. Once you’ve caught the grenade, turn towards the pile of debris blocking the entrance to the surgical wing and throw it. This clears the way for you to continue after Dr. Steinman. Load up on ammo and First Aid Kits at the vending machine and continue down the hall.
