- Rush tactic
This trick is useful for versus online multiplayer matches 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. On the other, build queue. Begin building a war factory. Place it, and begin 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, begin 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. However, this uses power and is not necessary. This tactic works best on Redzone Rampage since each player begins with boosts resources as the blue Tiberium. Nod is the fastest since it has the quickest build speeds. Also, build Predators instead of Scorpions. As soon as possible, place the 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.

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