Hint: Scrin: Placing buildings in thunder storm:
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.

Hint: Rush tactic:
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.
