Take the stairs

You decide to take the stairs.
You head downwards, toward the lobby. As you round a corner near the lobby, you are met with about twelve men all dress in black tatical uniforms. They're all armed with sub-machine guns and have a strange red and white insiginia. The leader of the group commands you to surrender. You're not particularly thrilled to see them, but don't know what to do. Instead of listening to them, you turn and flee. Gunfire erupts behind you, but you barely manage to throw yourself around the corner in time. You race upstairs, the soldiers right behind you. The chase eventually leads you to the roof of the building. With nowhere to run, no weapons and outnumbered, you finally decide to give up.
The leader of the group cautiously goes to you and proceeds to knock you out.
YOU HAVE BEEN CAPTURED.
