Tiberius unleashed an endless torrent of curses as the barrage of machine gun and assault rifle fire continued to pound his position.
"Jesus fucking Satan! Will they ever run out of ammo?!" He reached his hand around the corner of the wall and emptied another magazine from his pistol. "This is worse than five years ago!"

Five years ago: Tiberius sat hidden in a bush, happily eating a stick of salami and drinking vodka. Life had been going well for the last few months. He had almost one hundred and twenty thousand rouples to his name, a nice, new pair of military grade boots, plenty of ammo, and had recently repaired both his guns to near perfect condition.
As he ate, Tiberius thought about how great the Zone was. He got to kill people. He got paid to kill people. There was good vodka. Why didn't thousands of other people see the possibilities? But no, they sat at home doing their boring, normal, non-murderous jobs. Of course, new meat means more people, and he wasn't fond of that idea, but more people also means more people to kill, which he did like the idea of.

Tiberius suddenly found his thoughts interrupted by the feeling of being watched. But not just being watched, but being watched by many, greedy, devilish eyes. In fact, the feeling of being watched by so many unpleasant eyes prompted Tiberius to stand up out out of the bush and look around.
"Дерьмо."
He was surrounded by a pack of around twelve pseudo-dogs. He slowly reached for his kodachi and pistol, because things were about to become very unpleasant.

The present: Tiberius noticed that he'd managed to down a third soldier with his random firing, and at the same time pissed off the remaining two so much that they started lobbing grenades. Now trapped in a deadly game of hot potato, Tiberius concluded that he was going to kill the first asshole scientist he saw. It can't take that fucking long to open a door, can it?

Almost as if on command, the door to the lab swung open and a scientist motioned for him to run inside. Gathering his things, Tiberius jumped up and sprinted to the door. Once he reached it, however, he took cover behind it, checked his SVD's ammo, actioned the rifle, swung out and dropped to a knee, and blew a hole through the head of the fourth soldier. That done, he ducked into the safety of the lab with the scientist, whom he promptly glared at the scientist. once the door was closed.
"блядь."

The inside was just as boring as it always had been, except for one oddity. There was another STALKER already there. Slinging his rifle over his shoulder, Tiberius approached the man, crossed his arms, and asked, "Så hvem er du? Кто ты, Сталкер?"
