After retrieving the two access keys, I finally returned to the airship. Upon arriving, I found Robin already waiting for me.
To Opening the door to the secret vault requires using both access keys simultaneously and pressing two buttons at the same time. Robin's assistance was essential here.
Finally, we used the key together to open the door to the secret vault. After entering, the place struck me less as a prison and more as a haunted house. The hanging cells all around looked remarkably like coffins. The entire atmosphere was truly terrifying.
Robin and I slowly made our way into the Secret Vault. There was a separate cell for Killer Croc, but it lay in a state of complete ruin. going further inside, we discovered a secret laboratory.
Various recordings were playing on the TVs there. From them, we understood that the prison warden used to collect blood from Killer Croc. That blood was then injected into the prisoners to conduct various experiments. They were attempting to create a new type of gene, but their experiments were unsuccessful. Many prisoners died.
Seeing all this, I had no desire left to save the Warden. I felt like just leaving him to Killer Croc. But Batman is Batman. To him, saving everyone is a duty.
Meanwhile, Robin began gathering crucial data from the lab's computers so it could later be used as evidence.
After that, I entered a room behind the Robin Lab. That was where Killer Croc was holding the Warden captive. Several other prisoners who had joined Killer Croc's gang were around him.
We launched an attack on them without delay. But the fight was by no means easy. Killer Croc's DNA had been used on those prisoners as well, making them far more powerful. Even after being knocked out, they would get back up and attack again after a short while. We had to knock each of them out multiple times.
And right in front of me was Killer Croc himself. Due to his massive size, ordinary punches or kicks weren't very effective against him. However, Robin and I kept using our Dual Combat Attack. Our combo attacks resembled wrestling moves, and with every strike, Croc's health gradually began to deplete.
Killer Croc's attack was also terrifying. He would charge at us on all fours and pounce. But in the end, he could not withstand the teamwork of Batman and Robin.
We finally defeated Killer Croc using our Dual Attack. Afterward, we rescued the Warden. He was happy to see us, but Batman punched him and knocked him out.
After that, I returned to the GCPD in the Batwing, bringing Killer Croc and the Warden along. There, I handed both of them over to Cash.
And just like that, Killer Croc's mission came to an end. The terrifying secret of the Secret Lab was finally revealed to everyone.
