Simple guide on how to kill the Grenade Launcher Boss you meet in the game.
Preparations
Phase One
Starting off with grabbing the second egg and putting it in the Boss itself, you must be prepared to Dodge and Weave its attacks. The Fetus Launcher will fire 9 – 10 shots, and during that time, your best bet is to simple dodge the grenades. You can also use the two environmental objects that hold many limbs to hide behind while the boss is trying to get you.

After some dodging, and just avoiding the grenades in general, the boss will reload its launcher by taking ammo out of the its backpack full of ammo, during this you’ll see two Red Blobs on both the left and the right of the boss. Those are the Weak Points of the boss. Shoot them with the Pistol or Shotgun or use your Melee weapon that extends out to destroy those weak points.

After you’re done destroying the Red Blobs, the boss will fall to the floor, make sure to interact with his grenade launcher to activate Phase Two.
Phase Two
- The Boss will open up the spot where you originally put the Fetus Egg at.
or
- The Boss will not open up the spot where you put the Fetus Egg at.
If the boss does not open up the spot where you originally put the Fetus Egg at, QUICKLY RUN AWAY. But if the boss does open up the weak spot, quickly shoot it with the Pistol or the Shotgun. You will have to do this twice (or twice for me because I used the Shotgun.)
After shooting the weak point for how many times you needed, the boss will stop attacking and finally go down for the count. You can now take the Grenade Launcher as your reward and the Fetus. Take the Fetus back to the Fetus Grinder 9000 to get the blood you need to progress. And when you do that you must go back into the Boss room where you’ll find a pressure plate that you’ll need to stand on for a bit (it’s located to the right of the room). The wall will open up in front of you, you will have to shoot a Grenade into it. If you have no grenades because you shot it too many times, you can just go back to the Boss, which should has its backpack’s lid off. You can take ammo from there. When you do shoot the wall, the gate to the left will open up, revealing another Fetus Egg that you will need to crack. Go to where the machine was, not the Fetus Grinder 9000, but the boss machine. Simply put the Egg in there to begin the Second Boss.

The Boss will die, and the Fetus will craw out. Grab the Fetus and take it back to the Fetus Grinder 9000 to get the last amount of blood you need.
