There is armor and a log. After that, you’ll go with O’Neal to an elevator. Make sure you stand on the elevator with the button to your left. Then you’re gonna wanna run. A lot. Once you’re on the ground floor, head back the way you came to find some stairs. Once you break out into the open, it’s a cluster. There are marines and xenos everywhere, including spitters.
