Open the voice guide →Darkness changes how you read a room. Flashlight discipline—when to sweep, when to click off, and how to share responsibility—often matters more than raw aim. Expect battery tension to show up in routing decisions.
See items and light tips →Medkits are rarely infinite. Teams that win messy situations usually agree on a simple rule: who gets healed first, and when a heal is not worth the time lost.
Read the items guide →Learning a map is less about memorizing every spawn and more about building a mental checklist: where you rotate when something goes wrong, and which rooms are worth skipping under pressure.
Explore the maps guide →Four players means four chances to forget a step—door discipline, rear security, and agreeing on a retreat phrase. The guides section includes team habits that cost nothing but save runs.
