Engine
- reflection: dumpsters, eyes, hazard suit gloves, floors (tile, metal), glass, most metallic surfaces, rollers, sawblades, sewer pipes, shelves (metal), toxic waste, walls (some), water (+ puddles), weapons; pixel shaders; see environmental texture mapping
- shadows: vertical angle adjustment, fading; NPCs, moving objects
- skeletal animation: yes
- texture: 16-/32-bit depth
- filtering: bi-/trilinear
- mapping: bump, environmental, mip, procedural
- decals: blood/guts, bullet holes, crowbar impacts, explosion blasts, paint splats
- transparency: fire, glass, light beams, projectile trails, smoke, steam, video screens, water
- other: pixel/vertex shaders (reflections)
atmospheric/environmental effects
- dust: impacts, lightbeams
- lightbeams: windows (some), scanner drone lights, spotlights
- particle effects: debris, dust, gas, mist, smoke, sparks, splash, spray, steam, swarms
- shaking: bullet impacts, explosions
- shards: glass, metal, wood
- smoke: fire, shot NPC machines
- sparks: electricity, metal impacts (bullets, crowbar, manhack blades, etc), teleporters
- steam: some pipes
- weather: fog/haze
- wind: powerlines
- other: door handles/pushbars move, explosions, fire, gas spray, helicopter dust/spray, projectile trails, radiation mist, scanner drone swarms; see particle effects, physics, and sound
lighting
- dynamic
- colored
- vertex & lightmap
- coronas
- flickering
- electrified fence, eye scanner, fire, flashlight, manhacks, scanner drones, vehicles, windows
physics
- Havok
- gravity: characters
- air density, bouyancy, friction, inertia, magnetism, momentum, weight
- weight: player character breaks wood crates/beams and glass windows
- collision detection
- ragdoll bodies
- cardboard boxes break apart yet stay connected at seams
- turnstyle turns, signs swing
- plastic crates hold objects (bottles, cans, etc)
- powerlines move when hit
- power cables move around when power plugs/teleporter/TVs moved or from spark force
- explosion force pushes/breaks objects
- fire breaks wooden objects
- slippery sludge/oil
- steam pushes objects
- paint covers most objects
Character
player character
- facial animation, hazard evacuation (HEV) suit, view (white: scanner drone picture snaps, red: pain)
- footsteps: concrete, dirt, gravel, metal (duct, generic, ladder), sand, tile, water, wood

- view: 1st-person (3rd-person with cheats)
NPCs

Environment
- # levels: 68 (15 chapters)
- locations: canals, towns, coast, train station, prison, City 17 (Eastern European-style city), citadel
- cutscenes: yes
- level editor: Hammer?
- puzzles: physics-based (add/remove weight, add floating objects to surface something, etc)
- traps/hazards: drowning, electricity, explosions, falling (elevator, smokestack), fan blades, fire, getting burnt/cut/crushed/hit/shot, radiation, steam, toxic waste, trains
interaction
