Outpost 2 Tech Trees can be highly customized for individual scenarios. Each tech tree is a a .txt file that is parsed by Outpost 2 and may be used by multiple scenarios.
Outpost 2 shipped with several different tech trees. Each of these can be used on a new scenario instead of designing a new tech tree. Tech trees pre-included with Outpost 2 game distributions are often stored in .vol files. The Outpost 2 Mapmaker can be used to extract the tech trees from the vol files. The following tech trees are widely used in Outpost 2 scenarios:
MULTITEK - Standard tech tree for colony and multiplayer scenarios.
MULTITEK2 - Outpost Universe modified tech tree for colony and multiplayer scenarios.
survtech - Outpost Universe modified tech tree designed for survivor style multiplayer maps.
edentek - Eden campaign tech tree.
plytek - Plymouth campaign tech tree.
basictek - Multitek style tech tree that includes the Basic Lab research.
dteke - Pre-release Eden scenario tech tree.
* dtekp - Pre-release Plymouth scenario tech tree.
* dtek_m - Pre-release multiplayer scenario tech tree.
Each technology has a name and a 5 digit number that are defined on the same line as BEGIN_TECH. The 5 digit number is used on other parts of the tech tree to identify prerequisites. It is also used by the Outpost 2 SDK when designing scenarios to identify the technology for triggers and other in game purposes.
It is possible to assign the same name to multiple technology descriptions. This is used to alter the results of the technology based on the faction researching. For example, Hypnopaedia is both tech 05309 and 05310 since the time to train scientists is reduced more for Eden than for Plymouth when researched.
WARNING: If you wish to modify an existing tech tree file, ensure you change the name first. Otherwise, when you modify the tech tree file, it will modify all scenarios already linked to the tech tree.
===== Tech Tree Sample Entry =====
<code>
BEGINTECH “Advanced Vehicle Power Plant” 03901
CATEGORY 4
DESCRIPTION “Cargo Truck, Robo-Dozer, and Earthworker speeds improved. The new R-3000 series cool-fusion plant has been installed in all Cargo Trucks, Robo-Dozers, Earthworkers, replacing the earlier R-2000 model. This application of the High-Temperature Superconductivity technology has increased the speed of these vehicles.”
TEASER “Improves Cargo Truck, Robo-Dozer, and Earthworker speeds. _ Several of the vehicle models we use are powered by the R-2000 cool-fusion plant. Our work in High-Temperature Superconductivity may be applicable to an improvement of this power plant.”

===== Tech Tree Syntax =====
==== Comments (;) ====
Semicolons (;) are used to designate comments. Place a semicolon at the beginning of a line to designate the entire line a comment.
Example:
<code>
; Outpost 2: Divided Destiny
; Research : Multiplayer Game
</code>
==== Plymouth & Eden Cost ====
Use the keywords EDENCOST and PLYMOUTHCOST to set the amount of 'research points' required for each faction to gain the technology. Setting the cost to 0 or -1 for a faction will make the associated technology not available for them to research.
==== Technology Category ====
Use the keyword CATEGORY to place the associated technology into a category group. These categories can be used in a scenario to limit the technology available during the scenario, similar to the original Eden and Plymouth campaign scenarios.
==== Description ====
Use the keyword DESCRIPTION to add a short post-research description to what the technology does. Usually more specific than the teaser.
==== Teaser ====
Use the keyword TEASER to set a short pre-research description of what the technology may offer if researched. Usually less specific than the description.
==== Max Scientists ====
Use the MAX_SCIENTISTS keyword to set the maximum number of scientists that can concurrently research the technology.
==== Prerequisites ====
Use the keyword REQUIRES and then follow with the ID of the technology required as a prerequisite.
Example:
<code>
REQUIRES 03402
</code>
==== LAB ====
Use the LAB keyword to set which in-game Laboratory can research the technology.
^Value^Lab^
|1|Basic Lab|
|2|Standard Lab|
|3|Advanced Lab|
==== IMPROVE_DESC ====
Use IMPROVE_DESC to set the phrase that will display on units affected by an upgrade provided by the associated technology.
==== UNIT_PROP ====
Use to set a new value for a property associated with a unit. UNIT_PROP may be used multiple times within a technology.
Example:
<code>
UNITPROP BIGTRUCK Move_Speed 3
