Endless Apocalypse, Born Towards the Sun

A sudden zombie crisis full of "game rules". It's not a natural outbreak, but more like a "survival game" with clear rules, prompts, and levels. 10,000 People were selected and forced to participate. At the beginning of the game, all modern communication tools have been confiscated. According to the floating prompt word in front of you - "Towards the direction of the sun", you can run and escape endlessly.
