In this article I will try to explain strategies an tips about how to play with the GDI. At the first section I will explain to you how o construct and expand your base and how to use GDI army effectively. At the later section I will explain some tips to deal with another GDI, the Nod and the Scrin.
GDI General Strategies
In this section I will explain to you the general strategies and tips to play with the GDI. First is the very start of the game. At the beginning of the game try to build in this composition:
- 2 refineries. Place your refineries at tiberium depot inside your base.
- 2 power plants
- barracks. Start to build your infantry.
- crane
- surveyor. Send this surveyor to nearest tiberium depot that is not in your base.
Start to expand your base as soon as possible. Start making a lot of infantry and turrets. Do not forget to garrison your infantry in order to maximize their effectiveness. If you use this strategy, you will get a strong start to kick off the rest of the game.
To build your defensive army group use 4-6 Predators and 2-4 APCs with missile squads or zone troopers inside. Both vehicles appear to travel at the same speed, so one group wont get there and get all shot up before the other guns get there. Upgrade the Predators with rail guns as soon as possible. Mammoths are your best defense once you can get around to building them.
To create a good defensive position with the GDI, deploy one rig and two Mammoths. Set both of your mammoths to the hold ground defensive stance, to keep them right next to the rig. Once in a while go and use the repair button on the rig, but usually those 2 mammoths have taken out every wave the enemy throws at it.
At late game, the enemy usually will a lot of air attack. Build a lot of AA gun behind you in order to prevent enemy's air attack.
To build your offensive army group use about 10-15 Mammoths, try to combine them firehawk strikes on critical structures such as super weapons or construction yards. Use the firehawk's stratofighter ability to knock out construction yards, with stratofighter you can appear right next to their construction yard.
Orcas are another great supporting unit for mammoths. You can use them to take out beam tanks for example. Orcas are also able to detect stealth units, so they can find cloaked avatars, stealth tanks, anything that might threaten your mammoths.
Use your zone trooper drop pods power on the back of the enemy base before an attack. You may be able to knock out enough power plants to put them below their required power. If you can attack your enemy when they have lack of power supply, you can kill their base defenses with little resistance.
Keep your infantry out of Tiberium. Because being in tiberium will steadily damages most of your infantry units.
How to deal with another GDI
In this section I will explain how to deal with another GDI. Have similar units with your opponents will become your main problem. Learn your unit ability carefully and try to find a way to encounter them. For example encounter enemy's infantry with your snipers, and enemy's snipers with your vehicles, destroy enemy's vehicles with your missile squads etc.
Try to build your tech level faster than your opponents. Because both you and your opponents have exactly the same units, you need to use something they can't match. By building your tech level faster you will be able to use your advanced vehicles to attack them, before they use those same vehicles against you.
Set up a lot of AA inside of your base to prevent your opponent of using fire hawks.
Beware of their sonic cannons especially when you use your mammoths near enemy bases. Sonic cannons will blow your mammoths. If you group them up, you may even lose several of them in just a few shots.
How to deal with the Nod
In this section I will explain how to deal with the Nod. A good Nod player usually will use Fanatics extensively against you for anti-vehicle and anti- building purposes. To encounter their fanatics, make some extra snipers and scatter them around your base, and also send them with your attack forces. You will need them to kill fanatics.
Beware of the Nod's stealth towers. Approach their stealth towers cautiously and try bombard it in advance. Usually the enemy has placed a lot of turrets under the stealth field. They will destroy you if you approach them incautiously.
The Nod is the master of diversions. A stealth tower may just be a diversion to make you advance more cautiously, and miss other opportunities while you concentrate.
Each Nod AA tower can fire three missiles, and each one they buy comes in a set of three turrets. Don't use air attack if the enemy has a lot of AA towers, unless you are ready to lost a lot of your air unit.
How to deal with the Scrin
In this section I will explain how to deal with the Scrin. The Scrin have absolute domination in air power. So do not try to control the air.To support you Anti Air defense, put some firehawks in Anti Airmode around. These firehawk will deal with anything that your AA defense can't handle.
Build as many bunkers as you can. Put with missile squads, AA turrets, pitbulls, etc, inside of them. Without effective air power, you can force the Scrin to fight you on the ground, where your units are far more resilient.
