 - Игра активно и обильно течёт по памяти, оставляя после чтения файлов их `MapViewOfFile` и подобные штуки.

-
-## Как работает игра
-
-Главное меню:
-
-Игра сканирует хардкод папку `missions` на наличие файлов миссий. (буквально 01, 02, 03 и т.д.)
-
-Сначала игра читает название миссии из файла `descr` - тут название для меню.
-
-- Одиночные игры - `missions/single.{index}/descr`
-- Тренировочные миссии - `missions/tutorial.{index}/descr`
-- Кампания - `missions/campaign/campaign.{index1}/descr`
-  * Далее используются подпапки - `missions/campaign/campaign.{index1}/mission.{index2}/descr`
-
-Как только игра не находит файл `descr`, заканчивается итерация по папкам (понял, т.к. пробуется файл 05 - он не существует).
-
-Загрузка миссии:
-
-Читается файл `ui/game_resources.cfg`
-Из этого файла загружаются ресурсы
-- `library = "ui\\ui.lib"` - загружается файл `ui.lib`
-- `library = "ui\\font.lib"` - загружается файл `font.lib`
-- `library = "sounds.lib"` - загружается файл `sounds.lib`
-- `library = "voices.lib"` - загружается файл `voices.lib`
-
-Затем игра читает `save/saveslots.cfg` - тут слоты сохранения
-
-Затем `Comp.ini` - тут системные функции, которые используются для загрузки объектов.
-
-```

-## Загрузка `cp` файлов
-
-`cp` файл - схема. Он содержит дерево частей объекта.
-
-`cp` файл читается в `ArealMap.dll/CreateObjectFromScheme`
-
-В зависимости от типа объекта внутри схемы (байты 4..8) выбирается функция, с помощью которой загружается схема.
-
-Функция выбирается на основе файла `Comp.ini`.

-
-### Описание ниже валидно только для моделей роботов и зданий.
-##### Land.msh использует другой формат, хотя 03 файл это всё ещё точки.
-
-Загружается в `AniMesh.dll/LoadAniMesh`
-
-- Тип 01 - заголовок. Он хранит список деталей (submesh) в разных LOD
-  ```
-  нулевому элементу добавляется флаг 0x1000000
-  Содержит 2 ссылки на файлы анимаций (короткие - файл 13, длинные - файл 08)
-  Если интерполируется анимация -0.5s короче чем magic1 у файла 13
-  И у файла есть OffsetIntoFile13
-  И ushort значение в файле 13 по этому оффсету > IndexInFile08 (это по-моему выполняется всегда)
-  Тогда вместо IndexInFile08 используется значение из файла 13 по этому оффсету (второй байт)
-  ```
-- Тип 02 - описание одного LOD Submesh
-  ```
-  Вначале идёт заголовок 0x8C (140) байт
-  В заголовке:
-  8 Vector3 (x,y,z) - bounding box
-  1 Vector4 - center
-  1 Vector3 - bottom
-  1 Vector3 - top
-  1 float - xy_radius
-  Далее инфа про куски меша
-  ```
-- Тип 03 - это вершины (vertex)
-- Тип 06 - индексы треугольников в файле 03
-- Тип 04 - скорее всего какие-то цвета RGBA или типа того
-- Тип 08 - меш-анимации (см файл 01)
-  ```
-  Индексируется по IndexInFile08 из файла 01 либо по файлу 13 через OffsetIntoFile13
-  Структура:
-  Vector3 position;
-  float time; // содержит только целые секунды
-  short rotation_x; // делится на 32767
-  short rotation_y; // делится на 32767
-  short rotation_z; // делится на 32767
-  short rotation_w; // делится на 32767
-  ---
-  Игра интерполирует анимацию между текущим стейтом и следующим по time.
-  Если время интерполяции совпадает с исходным time, жёстко берётся первый стейт из 0x13.
-  Если время интерполяции совпадает с конечным time, жёстко берётся второй стейт из 0x13.
-  Если ни то и ни другое, тогда t = (time - souce.time) / (dest.time - source.time)
-  ```
-- Тип 12 - microtexture mapping
-- Тип 13 - короткие меш-анимации (почему я это не дописал?)
-  ```
-  Буквально (hex)
-  00 01 01 02 ...
-  ```
-- Тип 0A - ссылка на части меша, не упакованные в текущий меш (например у бункера 4 и 5 части хранятся в parts.rlb)
-  ```
-  Не имеет фиксированной длины. Хранит строки в следующем формате.
-  Игра обращается по индексу, пропуская суммарную длину и пропуская 4 байта на каждую строку (длина).
-  т.е. буквально файл выглядит так
-  00 00 00 00 - пустая строка
-  03 00 00 00 - длина строки 1
-  73 74 72 00 - строка "str" + null terminator
-  .. и повторяется до конца файла
-  Кол-во элементов из файла 01 должно быть равно кол-ву строк в этом файле, хотя игра это не проверяет.
-  Если у элемента эта строка равна "central", ему выставляется флаг (flag |= 1)
-  ```
-
-## `.wea`
