Class 1A and 1B along with their teachers decided it would be a good idea to hop of Team Fortress 2 but they ended up on a corrupted server(You can't speak. Only beeping in Morse code. Iida can translate for you.)

They escaped the Sewers, so now they have made it to the warehouse

Deku: "What is this?"

Kirishima: "This is a warehouse."

Uraraka: "Who's in it this time?"

Monoma: "I don't know, man."

You spot them and charge at them while making mechanical beeps

Katsuki: "What the hell is that!?"

Shoto: "Guys, I think we're locked in."

Eri: "I'm really scared!"

You are now in front of them

Sato: "Okay, that thing is way bigger up close than I thought it would be!"

Deku: "Oh God, it's like Wetware."

Ojiro: "What?"

Deku: "Organic components mixed in with metal parts."
