The timer was leaving the named vehicle on the pad and creating another on top of it. The home now follows that named vehicle, and a pad that already has one does not get a second.
Video Setup > FOV and Viewmodels > Legs, off by default. In first person the
player's own body, which the game animates as everyone else sees it but does
not draw for its own player, is drawn from the waist down: looking down,
your legs walk, run, strafe and crouch as the body's animation moves them.
How it is drawn (port/linux/game/first_person_legs.c):
- A copy of the body's pose as drawn: everything but the hips and legs (by
node name: pelvis, thigh, calf, foot, toe) folded into a lid over the
waist, the root kept.
- The body set back behind the eye, each frame, as far as keeps the waist's
open rim beyond the bottom plane of the view (the way Halo 2's fp_body
keeps its open top out of sight): looking ahead, 4 cm; straight down at
105 degrees, about 67 cm. The legs are seen as they swing forward.
- Drawn with the world's camera, so it keeps its place and size at any FOV;
not in mirrors, not in the shadow pass, without what it carries.
The waist's rim is found from the model's own triangles: object_mesh.c reads
an object's drawn mesh (its most detailed geometry, in the permutations it
shows) from the vertex and index buffers the game draws it from, as
powerup_render_bounds.c reads them; its cache is forgotten on a new map
(objects_initialize_for_new_map).
Only the drawing changes: the body, its hit boxes, markers, the camera and
everything sent between machines are the game's. Checked by compiling the
changed units; the fold and set-back were checked against a capture of the
cyborg's mesh and pose and played on Windows.

The scenario's tag name was copied with strcpy into the game state
header's 256-byte map_name, a tag's name was formatted with sprintf into
the out of objects message's 512 bytes, and csprintf bounded its output
at MAXIMUM_STRING_SIZE even when it formats into temporary, which is 256
bytes and where most callers put tag names. All three are bounded by
their buffers' sizes now.
The cache is forgotten before every game state load (beside cluster_partitions_port_forget) and at each new map, after the declarations, rather than at the top of four functions.
objects_port_set_activating_cluster takes the cluster a co-op host sends
in its presentation (network_coop.c), and refused only NONE and indices
past the BSP's clusters. Any other negative value (activating_cluster is
sent plus one, so a host sending -5 or 0x8001) was stored, and the client
then read the cluster PVS before the start of its array. Any negative
index now means none, as NONE already did.
A collision query (collision_get_features_in_sphere) reads the bounding
sphere of every collideable object in every cluster it touches, to pass
over the far ones. Every biped queries each tick, so a crowded cluster
(co-op's extra enemies, a carrier burst) costs the square of the crowd in
scattered object reads.
object_bounds_cache.c keeps the spheres packed by absolute index, written
by their only writer (object_compute_node_matrices). The loop runs the same
point_in_sphere on the copy, so the same objects are passed over and the
same features gathered, in order. game_state.c invalidates the copy when
the game state is replaced (revert, loaded core or game, new map).
Deterministic offline crowd (c20, legendary, extra enemies x8, 24 carriers
burst, seed pinned): game state identical tick for tick; collision queries
4.2 -> 3.0 us (-28%), object updates -15%.
Garbage (bodies, dropped weapons) is kept while a player may see it: in any player's potentially visible clusters, near them or in a 45 degree cone of where they aim, however far. With many players spread over a level and many bodies (co-op's extra enemies), every body was seen by someone, nothing could go, and the whole collection (each garbage object's visibility, the object memory pool compacted) ran again every tick on the host, which also wrote 'garbage collection critical' to debug.txt each tick while short of memory. A player now sees garbage no further than 30 world units off, a collection of active garbage that left too much is tried again only after a second, nothing collected compacts nothing, and the critical line is logged as often as the warning. Running short of memory or objects still collects at once.
With many enemies (co-op's extra enemies) object memory runs low and the
garbage collector prints "garbage collection critical" and "removing
objects" at every pass, filling the screen for the host and every client.
They are the game's own chatter, so they show as game.console_log says, as
the sound and texture caches' already do; the log keeps every line.
The campaign scripts only run on the host, against every player's unit,
but some of their habits assumed split-screen:
- volume_test_objects_all on the players waited for every player in the
volume at once: the Maw's bridge cutscene, a30's Pelican pickups. In
co-op one player arriving is enough now.
- Scripts name players as player0 and player1, so everyone past the
second was left out of what they did: Pelican loads (a30's pickups,
insertions), getting out, cutscene teleports and freezes, starting
profiles. Those players now follow player0 (coop_scripts.c).
- A cutscene filmed far from every player (b30's sword Elite at the
shaft door) wasn't active on clients: the cluster the scripts force
active (object_pvs_activate) now rides in the presentation's spare
bytes, and what the host's camera films is sent to clients as often as
what is next to their players.
- A mission the scripts fail (d40's timer, a50's Keyes) only respawned the
players, leaving them in the failure cutscene for good. It now reverts
like the cutscene skip does; everyone dying still respawns at the last
checkpoint. The scripts' game_revert reverts the same way.
The network version is unchanged: the presentation keeps its size, and a
host without the active cluster sends zeroes, which read as none.
Hosting a co-op level from the Map screen (CO-OP CAMPAIGN, a level and its
difficulty, then Server Setup) makes a network game on the campaign map
with no game engine, which is what co-op is. Only the host runs the
scripts and the AI; port/linux/game/network_coop.c sends clients what the
scripts do (cutscenes, camera, fades, HUD, sounds, devices, named objects,
animations), and network_actors.c drives the host's AI units on every
machine. Players spawn beside each other, respawn beside a safe teammate,
and spectate while dead or waiting. Skipping a cutscene is a vote.
Players can join a game in progress at any time.
An antenna's chain is a simulation of the Xbox's own step, an update a tick,
and the port was stepping it once a frame with the frame's own time. Its
springs, its carry and the points' physics then acted against the frames'
movement of it, so how far the chain moved per update depended on the frame
rate, and a vehicle at speed swung it far wider than a tick's step does.
- game.c steps the chain in the tick, beside the effects, which are already
stepped there.
- antenna.c records the shape each tick leaves, relative to the point the
vehicle's marker carries the base by. A frame drawn between two ticks is the
part of the way between those two shapes that it is, carried to where the
marker is now, so the chain stays on the vehicle it hangs from instead of
lagging a tick behind it. The gate that left a chain that had not been drawn
for five updates unstepped counted frames; it counts ticks now, which is
what it counted on the Xbox.
- widgets.c no longer steps the chain from the widget update, which ran once a
frame.
- game_time.c draws the per-frame effects and widgets that hang off objects
(game_frame) with the pose between the last two ticks, the pose the renderer
draws with, so what they place on an object is drawn where they put it.
- objects.c hands markers the matrices the renderer draws with, so an effect,
a particle system or a contrail attached to a moving object follows it
between the ticks too.

The Xbox game state (0x345000 bytes at 0x80061000) ends exactly where the
map-linked tag cache begins and has 948 bytes free, so a 128-player
session cannot even allocate its player datums. The native builds now
place a 16 MB game state (CPU 0xFC0000, GPU 0x40000) at 0x81A00000, above
the tag cache and below everything the Xbox memory window hands out
top-down, and grow the pools that scale with the number of players:
- objects: 2048 -> 8192 headers, 1 MB -> 8 MB pool; the garbage limits
keep January's proportions (5/10/20 % of the pool, 2.5/5/10 % of the
headers, 75/50/30 active garbage objects per 16 players)
- cluster partition reference lists 2048 -> 8192 (collideable and
noncollideable objects, lights); a full list drops objects out of
rendering, collision and sphere queries
- effects 256 -> 2048, effect locations 512 -> 4096
- particles 1024 -> 8192 (render_particles' visible list, filled without
a bound check, follows), particle systems 64 -> 256, their particles
512 -> 4096
- contrails 256 -> 1024, contrail points 1024 -> 8192
(MAXIMUM_CONTRAIL_POINTS stays the pool size for the same reason)
- lights 896 -> 4096, object looping sounds 1024 -> 4096
- cached object render states and rendered objects 256 -> 1024
- script object-list references 128 -> 1024, objects one explosion can
damage 64 -> 256
The values live in port/linux/include/halo_port_capacity.h, included by
halo_port_limits.h. With 128 player datums the CPU part holds 14,256,908
bytes (2,258,164 free). Saved games and cores grow to 16 MB. Every change
is under HALO_LINUX; the MSVC objects are unchanged.

cachebeta.pdb publics show 31 objects.obj symbols were file-static in
January, and no other January object references any of them. Only
symbols.json and our source disagreed with January.
- 29 functions were already static in our source; their symbols.json
entries gain "static": true.
- object_memory_release_procs becomes static.
- object_update becomes static, and its public prototype leaves the
shared objects.h. It is defined before every use in objects.c.
objects now matches January in all 225 symbols, all 121 functions stay
strict exact, and its 1,530-byte .data section is identical. It is
still held: five candidate-only helper COMDATs conflict with
hand-written NODUP providers (path_obstacles, action_charge,
player_control, bored_camera). It also emits the three stock D3D SDK
tables that keep rasterizer_xbox_profile held. No
semantic_data_matches entry, no credit.
Verification: full ninja (the objects.h edit rebuilt its 92
consumers); stable diff vs frozen 8,245-function baseline 0 gained /
0 regressions; parks 103/0/0; fake-match scan 0 -> 0; pytest 1154
passed; git diff --check clean.
