Tech lab (Tiberium Wars)

The Tech Lab is a Nod tech structure appearing in Tiberium Wars. Its primary role is to unlock the highest tier of units and structures in order to provide bases with more technologically-advanced weaponry.

Units and Structures
The Tech Lab is required to produce high-tech units such as Stealth tanks, the Specter Artillery, Avatar Warmechs, mantis, commandos, Purifiers, Vertigo Bombers, and Beam Cannons (though this was later transferred down to the Operation Centers in Kane's Wrath).

It also allows the building of the advanced structures such as the Obelisk of lights, Tiberium chemical plants, and the Temple of Nod with its nuclear weaponry guidance systems.

Building the Tech Lab in conjunction with the secret shrine unlocks the from the Hand of Nod.

Although the Black Hand subfaction does not use Vertigo Bombers or Stealth Tanks, construction of the Tech Lab gives them access to Purifiers.

Upgrades
The Tech Lab provides advancements to more "low tech" units: EMP coils, Spitfire laser capacitors, and Tiberium core missiles.

The Black Hand subfaction substitute Laser Capacitors with charged particle beams, while the Marked of Kane with supercharged particle beams.

Dozer blades were formerly available only from the Tech Lab but have since been moved down to the Operation Centers to make it earlier available to commanders (Kane's Wrath).

Support Powers
General Nod forces can use it to arrange the Redemption support power, where groups of militants and/or rocket militants within a designated area would be converted into The Awakened if killed. Neither the Black Hand, who refused to use "soulless machines", nor Marked of Kane, who already had Awakened cyborgs in abundance, employed this.

The Black Hand also use Tech Labs to project Decoy Temple of Nods, which appear to be real Temples of Nod to enemies.
