Stick with the team into the building, head up stairs, weld a door, and find the command center.
Follow the markers to start placing motion sensors. Use your tracker to find the locations and place them. Think it’ll be that simple? If you do, this must be your first rodeo.
Return to the morgue as ordered. And then you’ll need to return to the command center, when the place is filled with xenos. There’s no ideal way to do this, but go slow, keep a back to a wall, and don’t let yourself get surrounded. You’ll have to do some holding out when you reach the command center.
Then you have to run on an errand back the way you just came from to grab a sentry gun. O’Neal will cover you as you take it back to base, and you just deploy it where the shadow tells you. Then there’s another xeno wave, so get ready, as the auto gun only does so much good.
After your second stand in the command center, you’ll get a new job, and you’ll finally get one of those sexy smart guns. Awwww yeah.
Lemme tell you, using this gun is a pleasure. Follow the path, watch out for xenos, and enjoy the rewards. You’ll get the bonus for five gib kills if you didn’t already, and an achievement for kills via smart gun.
It ran out of ammo on my watch, so be conservative, but there are a ton of bugs. Follow the long hall to a bug room, and here you’ll have to kill a set number of xenos before you can move on. Put your back to a wall or door and hunker down. There’s precious little armor around, but a surprising amount of health. You’ll likely need a lot of it.
After the next door opens, move forward, around a turn, and when you reach a T-junction, look to the right. You will also see some armor and a Legendary weapon!
