According to my research, both games are using ASC files to control the operation of all units.

You can use any text editor to open these files with the suffix '.mdl', '.odl' and '.wdl'.

.mdl: the design of whole mission.
.odl: object model file.
.wdl: the coordinate and direction of static objects.

Unfortunately, I don't know how to check and change the coordinate of map. So the only thing you can do is change the type of weapons and units in the mission.

For example, this is data of a Commanche:

type "helicopter"
name "commanche"
schematic "schmatics\comanche-s.ppm"
objfile "pweapons\pcexport\comanche.ian" scale 10.2
objfile lod 1 "pweapons\pcexport\low\comanche.ian"
texture "pweapons\dsrtcam2.ppm" transparent
group "human"
hitpoints 150
points 500
sfx "helicopt" min 1000 max 12000 loop
dynamics "helicopter"

You can change the first line "type" to another unit or weapon.

Some units are only exist in a particular campaign. If you want to use them in every mission, then you must copy the object data to '.odl' file of other campaigns.


If you want to control a static object, then you must copy the "dynamics" data of other dynamic units. Such as this:

type "recpod2"
objfile "backgrnd\pcexport\level1\recpod2.ian" scale 14
objfile lod 1 "backgrnd\pcexport\low\recpod2.ian"
texture "pweapons\dsrtcam2.ppm" transparent
group "human"
hitpoints 200
dynamics "alien"
mass 115
max altitude 9000
min altitude 500
max vel 80
min vel 0
pitch acc 2.2
yaw acc 1.6
roll acc 3.5
linear acc 5
bank stability 60%
linear drag 40%
angular drag 40%

You just need to copy them and replace the original type in the mission files.

These units are hidden in the Incoming Forces. You must copy the data to a blank section of '.odl' files and delete some lines (like sfx, useranim, etc...), or game will be crashed.
