1 Overview
Technology Upgrade sectors are special research & development building complex sectors that can grant access to new type of vehicles, buildings, and many other valuable upgrades to a faction during the gameplay. Tech Upgrade sectors will provide certain upgrades to strengthen the player's arsenal once they are acquired by the player.
There are many different types of technology upgrades, as well as their sector layout types. The upgrades can be a new vehicle or a new building, an increase in firepower for a weapon, an augmentation of a shielding, or even an improved radar signal range. The technology upgrade sectors appear as a splashing sigma symbol on the map display.
2 Gameplay
The technology upgrade sectors must be first captured by the player's faction in order to gain access to their benefits.
Over the course of the single-player campaigns, the player will come across many different types of technology upgrade sectors. They are present in most missions and some of them do not directly appear on mission briefing by level design (usually for an extra difficulty). Because of their strategic values, they are most often heavily guarded by the enemy forces. The upgrades and effects gained via technology upgrades are permanent applied in the playthrough.
In multiplayer mode, all technology upgrade sectors only provide either a new vehicle or a new building upgrade for different factions that make appearances in the level. Therefore there is no extra weapon, shield, or radar upgrades available for the units. Additionally, some technology upgrade sectors in multiplayer levels will yield double technology upgrades from a single sector, usually one vehicle and one building type for different factions present in the level.
3 Mechanics
3.1 Single-player
In single-player campaigns, once the technology upgrades are captured by the player, their effects are permanently implemented to the player's technology progress, even if the player loses a control of the technology upgrade sectors. Therefore, there is no practical incentive to guard the technology upgrade sectors once they have been captured by the player at least once.
3.2 Multiplayer
In multiplayer levels, technology upgrades gained are not permanent, and are directly connected to the ownership of the factions who control them. Only the player who currently possesses a technology upgrade sector under their control will have access to the benefits of that technology upgrade sector.
For this reason, players will usually attempt to control more technology upgrade sectors so they can have access to more technology, while also simultaneously denying their access from the enemies. This design encourages additional layers of strategic values and factors during the multiplayer matches.
4 Appearance
The standard Technology Upgrade sectors are present in various types of special building complex sectors that are easily distinguishable from the other structures. The buildings appear to be based on libraries or laboratories facilities. In very rare cases, the technology upgrade sectors may be present in other special types of sectors, such as the Sphinx monument.
