To defeat the Beserker at the end of act one, simply dive to the side when she charges at you. Run through the doorway to your right and continue to the door at the end of the room and face your back to it. Get the Berserkers attention by shooting at her or revving the chainsaw then, dive away at the last moment when she charges causing her to break the door down for you.

Continue this to get through the next two doors. When you finally lure her into the courtyard simply use the Hammer of Dawn twice to take her down. If Dom is killed the mission is over, so revive him if he's knocked down.

The second one in Act 4 is defeated similarly. Defeating the second berserker. There are six stone supports for the second part of the greenhouse. Lead the berserker through the six supports, you will see glass dropping from the ceiling. Once all six supports have been taken out, two shots with the Hammer of Dawn will crisp her.
