UMBRA — 灯影突围

  Shoot out the lights. Break line of sight. Find your way out.  

 UMBRA is a single-player, top-down tactical shooter about light, sound and cover. A flashlight helps you see—and helps enemies find you. Break a lamp, close a door, slip around a corner and move quietly to shake the pursuit. When stealth fails, keep moving and fight your way to extraction. 

 Inside V08 R3 

 

 Ten progressively harder sectors, each with three combat waves and an extraction objective. Routes and obstacle arrangements vary between ordinary runs. 

 Nine weapons plus frag grenades, from a quiet tactical knife to shotguns and heavy firepower. Earn supplies to unlock more equipment. 

 Enemies that investigate sound, search with flashlights and share alerts with nearby allies. 

 Destructible lights, doors, movable crates and electric traps that affect how you fight and escape. 

 Between-wave upgrades, campaign challenge stars, 13 achievements and a local ranking challenge with a fixed map seed. 

 Optional aim assistance, remappable keys, reduced motion, bloodless mode and UI scaling. 

 

 How to play 

 Move with WASD , aim with the mouse, hold left mouse / J to fire and right mouse / K for precision aim. Use Space to dash, hold Shift to sneak, R to reload, F for the flashlight and E to interact. Switch equipment with Q , the mouse wheel or 1–0 . Esc pauses the action. Keys can be changed in Settings. 

 Touch layout: move with the left stick; hold the right attack pad to fire and drag it to aim. Dash is on the right. Nearby buttons control reload, stealth, flashlight, doors and grenades. Landscape provides a wider view. 

 Clear three waves, choose an upgrade after the first two, then hold the green extraction point for 0.75 seconds. Supplies and campaign progress are awarded on successful extraction. After defeat, retry the same map and use the debrief to adjust your approach. 

 Current version 

 This is an in-development browser release. Progress, achievements, settings and rankings are saved in this browser; there is no account sync or global leaderboard. Refreshing returns to the start screen rather than resuming an active fight. Clearing browser data can remove the save. 

 Chinese is the primary language. English covers the core menus, tutorial and run flow; some extended guide and archive text remains Chinese. The touch layout has been tested with Chrome touch emulation; physical iOS/Android testing is still pending.
