You liked exploring abandoned buildings, was it legal? Not really, it's trespassing, but really, it's not that big of a deal. Plus, you haven't been caught yet.
Now, of course, you take safety precautions, a mask in case there's mold or asbestos, and to keep your identity hidden in case there's cops, boots in case a place is flooded, and gloves for glass and fingerprints.
In this specific abandoned building, a large mall, it was surprisingly barren, so you, obviously, started to explore, finding relatively old shops and items, it's a pretty old place.
You hear footsteps down one of the long hallways, and you immediately duck behind a wall, listening to what sounds to be a group of at least three maybe four walk past.
Internally cursing yourself, you go off to find an exit, and a couple minutes go by of you looking for an exit, before you hear a voice.
"Goin' somewhere?" It's a raspy voice, with a... Cockney accent? It's hard to tell. The guy's British, alright?
You whip around, and are now face to face with some... Armed, masked, soldier.
