Though huge, it is very easy to kill. Note: The following was done under the Medium difficulty setting. When the fight begins, notice that you are "caged in" by the Boss' tentacles. Shoot the yellow "blooms" around the Boss' mouth. However, upon shooting a couple of them, the boss grabs you, holding you in the air. During this time, it appears that you are helpless. Aim whatever weapon you are using at the time and shoot the yellow blooms. After a couple shots you will be dropped. The Boss will then start slamming its tentacles at you more frequently. They are very easy to avoid. Strafe left to right constantly. They will never hit you. The Boss will roar, shoot a few exploding cells at you, or will drop enemy pods upon you. This is part is also easy, considering it is usually only two small Necromorphs. After destroying the blooms, you will notice a "caged" area underneath the beast. Under this rib cage lies its many hearts. Again, use same strategy with the whole tentacle scenario. After a few times, the Boss will have his fit and open up again. Unload and the Boss will come tumbling down.
