Threat Rating Node upgrade

The Threat Rating Node (TRN) was an upgrade for the GDI Adv. comms and GDI Upgrade center. It was Basicaly a extra computer which preformed calculatons based on the threat values of units and adjusted AI weapon targeting of player controled units and structures accordingly.

This meant for example a Nod stealth tank would be targeted by a RPG tower over a group of light infantry as the stealth tank is seen as a bigger threat.

If conncidered cannon
It is possible the Threat Rating Node upgrade was fazed out before the start of the second tiberium war due to improvments made to EVA's AI allowing it to make better and more logical decisions with out the aid of extra computers.

During the firestorm the TRN upgrades were kitted with the nessasary equipment to allow the commander to call in Droppods, perhaps a sign of how rushed the deveopment was on many of the units and structures mass produced during the firestorm Crisis.

Ingame
The Threat Rating Node can be seen on several Custom maps and can easly be made buildable to GDI players via mods or map edits. As well as the Threat rating not being correctly codded in the .ini files there is a problem where if the upgrade is sold or destroyed the new threat rating values are not "unloaded" by the game.

Althought the Droppod node upgrade uses the same graphics as the TRN it doesnt replace the TRN meaning there are four upgrades for the upgrade center ingame in firestorm.

In unpatched Tiberian Sun a TRN needed to be constructed else the Hunnter seeker superweapon would not pick targets correctly and was known to attack civilians. Due to the TRN being cut form the game possibly/most likly late in development it was only made unbuildabe and it was not until one of the first patches that the Hunnter seeker superweapon was edited to correctly operate with out the TRN.
