About 死寂(Deathly Stillness)
Deathly Stillness is a third‑person zombie shooter created as a teaching case by bilibili creator Chen Jiacheng. The game offers no narrative, focusing solely on the task of eliminating every zombie across two maps. It is free on Steam, runs on Windows, and supports single‑player with partial controller input.
Players must scavenge for ammunition, avoid the lack of health packs, and can unlock a one‑hit melee skill after a series of attacks. The title showcases rapid development, having been built in just 17 days and released for fans to experiment with Unreal Engine techniques.
01 / THE GUIDE
Gameplay Basics
The core objective is to complete the quest by killing all zombies. The game is presented in third‑person view and does not include a storyline, keeping the focus on combat. Players navigate two distinct maps, each offering weapons of varying difficulty.
There is no health‑pack system, so monitoring health is essential. The experience is intended as pure entertainment without additional narrative layers.
- Observe zombie patterns early to plan safe routes.
- Conserve health by avoiding unnecessary engagements.

Ammunition Management
Ammunition does not spawn automatically; players must search the scene for supplies. Without sufficient ammo, ranged attacks become impossible, forcing reliance on melee. The game’s design expects players to locate ammo before engaging zombies.
Because the game lacks health packs, running out of ammo can increase risk, making thorough exploration of each map critical for survival.
- Prioritize checking corners and hidden areas for ammo.
- Balance shooting with melee to stretch limited ammunition.

Melee Skill Trigger
Performing five or more melee attacks activates a skill that can kill a zombie in a single blow. This mechanic provides a powerful option for players who run low on ammo or prefer close combat. The skill is only available after the required number of attacks.
Utilizing the skill strategically can turn difficult encounters into quick victories, especially on maps with higher weapon difficulty.
- Chain melee attacks early to unlock the one‑hit skill.
- Save the skill for tougher zombies to maximize its impact.

Maps and Weapon Difficulty
Two maps are available, each paired with weapons of different difficulty levels. This allows players to select a challenge that matches their skill. The variation in weapon difficulty influences how quickly zombies can be dispatched.
Choosing a map and weapon combination that aligns with personal proficiency can make the experience smoother, especially given the limited health resources.
- Test each map with a lower‑difficulty weapon before advancing.
- Match weapon difficulty to your comfort with ammo scarcity.

Development Background
The game originated from a 2020 Bilibili live broadcast challenge to create a zombie game in half an hour. After several short improvement periods, the total production time reached 17 days. It was released on Steam in September 2021 to give fans quick access.
Chen Jiacheng handled all core systems—movement, pickup, shooting, damage, AI, and optimization—without templates. The project serves as a free teaching case for Unreal Engine learners.
