Command & Conquer 3 Tiberium Wars

This mission becomes a lot easier when you capture the Scrin base. The tactic to do this is when GDI sends its main attack force to the base consisting of the Mammoths, Predator tanks, Pitbulls, etc. Wipe these out with the Juggernauts or use the super weapons or bombers. When they are destroyed, they leave the Scrin base with no defenses which is perfect for you. Send in the Emissionary and start to deploy and set up your own Nod defenses. Also try capturing the Scrin airfield to the left and build the Scrin Construction yard. Use both Scrin defenses and Nod defenses to repel the GDI attacks. Use this tactic on the hardest setting and the mission becomes very easy. You will get control of the tower and will be able to withstand the attacks. Leaving the Scrin in control means the GDI will walk into the area and destroy the tower. You are now able to deploy Nod and Scrin units, making assaulting the GDI bases easier.

This trick is useful for versus online multiplayer with 10,000. Play as Nod or GDI and place a Crane. Then, build a Power Plant from each and place them. Once this is done, build two Refineries and place them. Next, sell one and build another. Then on the other, build queue. Start building a war factory. Place it and start to build another one. Make sure you have placed your second Refinery. Then, build two Harvesters from your War Factory. In the meantime build Refineries and a Comm Center. The moment your Harvesters are done, start building as many Scorpion Tanks as possible. Place other War Factories and Power Plants as well to boost production. It is also helpful to place an anti-infantry base defenses near your MCV to stop the "Engineer rush" tactic. This uses power however and is not necessary. This tactic works best on Redzone Rampage, as the blue Tiberium each player starts with boosts resources. Nod is the fastest, as it has the quickest build speeds. Also instead of Scorpions, build Predators. As soon as possible also place Tech Center and upgrade tanks with either Laser Capacitors or Rail Guns. This will not always work, especially when you face upper level players in the higher ranks. However it is possible to finish a battle in less than ten minutes with this tactic. It works best with 10,000, but can be done with more however it is harder as the opposition will have stronger weapons than you. It works well with 20 as you can use shortcuts and an extra Crane to boost production and speed of rush.

Build your base with heavy defenses. Nod attacks will intensify over time and the two Mammoths will quickly be overwhelmed by the superior Avatars. For an effective defense, capture every Avatar you encounter by killing it and reactivating the husk with an Engineer. After getting about thirty of them, counter-attack and destroy the Temple defenses. If you need more time, kill the Obelisks at the southernmost entrance, then sneak in with a Sniper Team to spot for Juggernauts firing from your base. Once the first Ion Field Disruptor is down, call in an Ion Cannon strike on the two War Factories at the south entrance to gain some time. Against infantry, use a similar tactic on the Hands Of Nod at the east entrance. Both entrances also have their own Air Towers.

Successfully complete the GDI and Nod campaigns.

When playing as the Scrin in either multi-player or Skirmish mode, it is usually not possible to place buildings within a thunderstorm produced by the Storm Tower. The trick to get around this is to power down the Storm Tower and place whatever you want next to it (for example, another Storm Tower). This strategy will help to improve your base defense.
