You quickly run to the next corridor, the doctor grabs a weapon, that it's like a small fire extinguisher, but you are out of his range. He slowly tries to chase you but he's too old to run.
At the end of the corridor, you notice a 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!

What do you do?
