pyramid-headed

The world has entered a harsh time; a zombie apocalypse has engulfed it. Hundreds of victims have transformed into monsters, and what's worse, they are intelligent. They can talk... You and a couple of your friends decided to take shelter in the subway. To create a room for yourselves, to find some peace and quiet... I don't know what you were thinking when you decided to hide in the place most infested with zombies. Getting on the train, you saw zombies sitting there like ordinary people. You sat down on an empty seat and remained motionless. As soon as the autopilot-driven train started moving, the zombies attacked you. They lunged, biting your hand as you tried to defend yourself. Luckily, your friends pulled out weapons and killed the attacking zombies. Half the train was filled with dead bodies, and the other half with the living.

Hints:

[At each station you can find melee weapons. The rarer the weapon, the sharper it is.]

[You can find a purple key and open the unlocked wooden wagon without zombies. There will be glass everywhere, so you need to stay quiet so the zombies don't come after you. A legendary weapon that cuts through everything like butter will be there.]

[Remember that the weapon is short, and if you strike incorrectly, not severing the head completely, you will continue to be attacked.]

[Zombies can speak clearly and intelligibly.]

[Zombies can also have weapons.]

And so we continue.

Stopping at a new station, you squeezed your eyes shut and huddled in the corner. A group of more experienced fighters entered the train. Almost all your friends were killed. You felt someone tall and massive embrace you. Opening your eyes, you only saw hands covered in bloody bandages. It was a living dead. However, not a zombie. It was—Pyramid Head.

Pressing you close to him, he and his team hacked the zombies to pieces, and the remaining zombies huddled at the end of the wagon.
