Scoped weapons hold breath with recovery feedback and sound. Riot shields block and deflect bullets in hand and on the back; explosive crossbow bolts, destructible map cars with round resets, and T5 map model collision work. Remote players show last stand, weapon change, jump, mantle, landing, ladder and stun animations, and server hitboxes follow the shared torso tree. GSC gains spectator follow cameras, chat, kick, vehicle paths and flight controls, physics spheres, slow motion, slide and mantle movers, damage triggers, music, ambience, rumble and live audio fades over a shared mixer. IW5 and T5 maps get sun shadows with per-stage sun selection; post-fx pipelines compile before a vision blend needs them. The lobby browser keeps focus and selection, and rooms can be password protected. Console supply and give commands search every item category. Frames and replays decode only the current wire protocol. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Portable Windows folder
make launcher windows creates dist/windows/iw4l-windows-{dev,prod}.zip. Both
archives use the password contextrot and are self-contained — the game binary
is inside, so the folder runs with no network at all.

The four licence files are not decoration: iw4l.exe has both fonts compiled in
with include_bytes!, so an archive carrying the binary carries their licences
too. release.rs::LEGAL_FILES is the list; a build shipping without them is a
bug.
Extract into any dedicated folder and add ordinary Windows .lnk shortcuts to
installed Call of Duty title folders or executables. MW2 Multiplayer files
are required for the menu (zone/**/common_mp.ff); zone/dlc/*.ff alone is
insufficient. BO1 and MW3 are optional. The launcher starts the game without
modifying those installations.
Updating is something you ask for. Plain iw4launcher.exe starts the
iw4l.exe already in the folder and touches nothing else. Fetching a newer
build is iw4launcher.exe update (or IW4L_UPDATE=1 for a shortcut that cannot
pass an argument), which needs IW4L_UPDATE_URL in the portable .env. No
build replaces its own binary on its own. Publishing is DEPLOY.md.
The folder holding the two executables is the process working directory even
when Explorer supplies another; IW4L_GAMES defaults to it, and .lnk targets
inside it are additional read-only search roots. .env is loaded before
release-manifest defaults, created only when missing and never overwritten.
.env holds IW4L_UPDATE_URL=https://host:8443/prod plus the master keys
from MASTER.md. An unreachable master is not a launch error: the browser keeps retrying. All
writable state stays below iw4l-artifacts/ (including settings.cfg, unless
IW4L_SETTINGS_PATH overrides it); shortcut targets are never output paths.
