I got separated from Ellie and started wandering around the Hotel Lobby to get to her as fast as possible but there were some special creatures that attacked me in the meantime.
After taking care of all the hunters in the hotel, we were looking for a way out and we found this scene where a couple probably tried suicide cause it seemed like the easiest way for them to die as clickers gives peoples hard death.
Ellie noticed a ladder inside the elevator there so Joel decided to try opening it and with my help, he opened it up and I climbed up the ladder to see where it goes. Probably the hunters used this ladder and left it behind.
We had to jump over another elevator and it looked like we were half floor down from the floor where we should've gone so I helped Ellie getting up again and suddenly the elevator went down and Joel was also falling down to his death.
No he didn't die as there were water below and he landed on the water. He let Ellie know that he's okay and asked her to stay up there as he'll make his way up to her.
Now I started swimming through the dirty water when it looked like a scary and dark underworld. I even noticed dead bodies in the water there.
I hardly found the way where I should've gone next but the gate was locked and I forgot how to dive when I had to dive in the water and get around through a hole. I remembered at last and I did it right.
I was walking through the darkness and suddenly some big rats ran through and spooked me. These rats reminded me of the rats of A Plague Tale that 
I ran through this alley that was full of the clickers element around the walls. I found a door behind me but it was locked so I started looking around.
Suddenly I found these special creatures who looked like clickers but they were not clickers. They didn't have eyes I guess but still they were coming towards me. There were 3-4 of them and I shot all of them down.
I found his door key card that I tried using on the locked door but the lock needs power and I was asked to activate a generator.
Now I started looking for a generator and I found one after searching thoroughly an I activated it after some tries. I'm glad that it had oil in it. Right after activating the generator, I heard clickers or those creatures screaming.
I didn't stay back to fight them, I ran to the door and I unlocked it and I locked it from the other side fast. Then I was climbing upwards and found the stairs were blocked at about 2 floors above. There I found a work bench which I used to upgrade my gun holster and now I can switch my weapons easily.
We'll check what happens next in another post.
