Dispatch the one or two enemies at the top of the lift, and recharge the PCV. You will hear gunfire from allied soldiers, but they will get killed. Go on the elevator and press the button to raise it. Otis will unlock a door containing a few grenades for an MP5 you'll pick up shortly. Jump through the window, and open the door for Otis. When you see Barney and a scientist talking, a new alien will appear and kill both of them. Be careful when fighting near Otis because he will shoot you if you stand between him and an enemy. Take him through the corridor, killing the headcrabs, zombies and hound eyes. Press E next to Otis to get him to follow you. Head around the corner and you will find an overweight security guard named Otis trying to steal from a vending machine. Kill them before picking up the glock, as it deals less damage. Originally, the G-Man was to be in the booth at the beginning of the chapter, staring outside, while straightening his tie. Just before you reach the Glock 17, two vortigaunts will teleport from the tram and attack the first will appear on the platform, and the other on top of the tram. In the SDK for Half-Life, the source files for the animations bear the prefix c1a3, which indicate that this scene was originally created for the chapter 'We've Got Hostiles'. Exit the platform and ready your shotgun.
