When you walk outside, Conroy and his pals will put you through a test and you’ll have to survive their hits for 30 seconds. Once you take out all of the enemies, you will finally meet Winston and he will ask you to do a job for him. Once you enter the building, a few waves of enemies will attack, showing you how to use your attacks and grapples.
