Stalker: Shadow of Chernobyl → Monolith Control
At first, you can stay within the room and into the corridor, luring the stalkers toward you and shooting through the metal bars.
Then, head left down the corridor, and after a few turns, you'll find yourself in front of a room with electronic "cabinets." There are several stalkers here; you can deal with them by throwing grenades into the room and carefully firing bursts, peeking around corners.
When the sixth pair of tori explodes, a green hologram depicting a scientist will condescend to speak with Marked One. The ghost will explain why the Zone was formed and who Marked One is, and offer a "red or blue pill"-style choice.
If the player accepts the hologram's arguments, the game will end with the first true ending. If not, they'll find themselves back on the streets, their heart burning with revenge. To the Chernobyl Nuclear Power Plant location.
