|
| Firestorm Generator |
 | Price: | 2000 |
| Weapon: | - |
| Armour: | Concrete, 700 |
| Power: | -40 |
| Description: The Firestorm Generator is an impressive structure in itself, although alone it is potentially useless. Used in conjuction with Firestorm Wall, it can project an almost inpenetrable defense. The generator drains an enormous amount of energy, and has to build up a store of high-energy plasma for use in the shield. The plasma also has a limited lifetime before it ionizes with the air and disipates, resulting in the wall having to continually be fed plasma until the generator reserves are depleted. Once the plasma reserves are depleted, or the projectors disengaged, the generator begins to create plasma again. |
|
| Firestorm Wall |
 | Price: | 500 |
| Weapon: | - |
| Armour: | Concrete, 1000 |
| Power: | -40 |
| Description: Used in conjuction with the Firestorm Generator, the Firestorm Wall when in use will project a field of high-energy plasma up into the atmosphere. This high energy field will vapourise and create an emp effect on any object passing through. This makes it impassable to "solid" projectiles as well as units. The firestorm wall will hold back ordinary Nod missiles. However, it has been found that energy-based weapons are able to pierce through the plasma with little difficulty. |
|
| Component Tower |
 | Price: | 500 |
| Weapon: | - |
| Armour: | Concrete, 800 |
| Power: | -25 |
| Description: The Component Tower is GDI's primary method of base defence. Although in its basic form it is useless, when upgraded with one of a selection of defensive turrets it becomes an effective method of defence. It can be upgraded with anti-infantry, anti-armour and anti-aircraft weaponry. This weaponry will change as technology improves. |
| Component Tower Upgrade - Vulcan Machine Gun |
 | Price: | 150 |
| Superweapon: | Vulcan Machine Gun |
| Armour: | - |
| Power: | -5 |
| Description: This is the simplest form of weaponry avaliable to the Component Tower. Cheap, low power drain, the Vulcan Machine Gun is doubled barrelled and fires rounds of bullets in seconds at hordes of infantry. Its bullets are small and are not designed to pierce armour and so are ineffective against armoured units. Replaced by Energy Cannon. |
| Component Tower Upgrade - Energy Cannon |
 | Price: | 250 |
| Superweapon: | Energy Cannon |
| Armour: | - |
| Power: | -15 |
| Description: The replacement to the Vulcan Machine Gun, but with similar properties to the Gauss Cannon. The energy cannon fires a small ball of plasma, which although no particularly good against heavy armour, can severely damage light armour melting it away, and will scorch flesh, making it a very effective anti-infantry weapon. Its plasma has a good rate of fire, but each shot has a slight spread meaning it is still effective against grounds of infantry. |
| Component Tower Upgrade - Gauss Cannon |
 | Price: | 250 |
| Superweapon: | Gauss Cannon |
| Armour: | - |
| Power: | -15 |
| Description: The Gauss Cannon is a new refinement of anti-armour weaponry. Firing a magnetically accelerated shell designed for piercing armour and making an impressive impact. Its explosive spread is minimal as it is designed for precise internal damage to systems as opposed to damaging a unit from the outside. An improvement in this technology is having a bearing projectile, in which it explodes before impact releasing high energy ball-bearings. These are able to pierce light armour and have a large spread. |
| Component Tower Upgrade - SAM Missile Rack |
 | Price: | 300 |
| Superweapon: | 2x SAM Missile |
| Armour: | - |
| Power: | -15 |
| Description: The SAM upgrade for the component tower remains mostly unchanged from previous deployment in the Second Tiberium War. Later improvements include range and firing multiple missiles in a barrage. Its targetting system is deployed against aircraft only. Replaced by Seeker EMP Missile Rack. |
| Component Tower Upgrade - EMP Seeker Missile Rack |
 | Price: | 450 |
| Superweapon: | EMP Seeker Missiles |
| Armour: | - |
| Power: | -25 |
| Description: Replacement for the SAM Rack, there are multiple advantages over this system. Firstly, a secondary targetting system has been setup, allowing the missile rack to target both ground and air units. The range for ground targets is very good, however it is not able to targets within a certain range to the tower. Secondly, the missiles contain an EMP warhead, this disables ground units for a short time, while disables the systems of aircraft, causing it to crash. |

| Pavement |
 | Price: | 75 |
| Weapon: | - |
| Armour: | - |
| Power: | 0 |
| Description: Pavement is used to prevent subterrenean units from surfacing in certain positions, as well as preventing terrain from deforming due to heavy artillery fire. Pavement also allows a speed boost for ground vehicles. |
|
| Wall |
 | Price: | 300 |
| Weapon: | - |
| Armour: | Concrete, 300 |
| Power: | 0 |
| Description: Concrete wall is used to help protect bases from attacks, or at least to hold back attacks long enough for defenses to be mobilized. GDI walls are bigger and steel-reinforced concrete allowing for a more durable construction. They are as a result, more expensive. |
|
| Gate |
 | Price: | 300 |
| Weapon: | - |
| Armour: | Concrete, 450 |
| Power: | -5 (but not powered) |
| Description: Gates are used to allow a passage way within a line of wall for friendly units to pass, while able to hold back enemy units. Although power draining, they are not dependant on power due to back-up generators built in. |
