Finish him

You slam his head again with the iron bar, he faints in a pool of blood, the doctor will never wake up again...

You quickly run to the last corridor in the lab.
At the end, you notice a huge rack full of strange eggs, also, there is a purple glowing portal close to the rack.

You are saved! you can finally return to your world!!

You start to think about your next move. You don't have time to waste!
