After a cutscene in which Kim dies, there will be another one. Welcome to your first boss battle. The locust have set a berserker loose in the building, a creature intent on destroying everything in its path, it can't see, so it hunts by smell and hearing. In the cutscene, one of the generic "Carmine" soldiers will try to make a run for it; it doesn't end pretty.

Your first stop should be going over to where the soldier was ripped to shreds, among some small fires, you'll find a set of COG tags. After that, pick up the hammer of dawn near the entrance and get ready to do some dodging, because you need to lead the berserker outside in order to kill it.

After a wee bit of walking on foot, the berserker will crash through the wall in front of you, sneak by it and go to the right... to find a dead end. What you need to do here is get the berserker to charge the door, so get its attention by revving the chainsaw bayonet, then at the last moment, dive out of the way.

You'll need to do this three times, each with slightly smaller rooms. On the last one in a window to the left of the door, pick up another COG tag. Finally, when you get outside, its time to lay down the hammer.

Immediately run to your left to the fourth planter, behind it, you'll find the final COG tag of this level. Afterwards, using Dom as bait, drop the hammer on the berserker, be careful, because it will charge once it hears the beeping. Three shots with the hammer will kill it, but if you hammer it once, then run up and grenade tag it while its stunned, then this will also kill it faster and easier.
