Starting Prestige Cheat
The Starting Prestige cheat allows you to determine the number of prestige points you start your game with. Ordinarily, this value is only 50 prestige points, a sum only large enough to restock your ship's supplies or repair its hull. To change this value, open your Starfleet Command II directory and navigate to MetaAssets/ServerProfiles/SinglePlayer. Find the file labeled "Character," make a backup copy if you like, and open it using NotePad or WordPad.
Now find the line that reads "StartingPrestige=50" and change the value "50" to any number up to "5000000," a sum large enough to purchase a fleet of dreadnoughts and keep them repaired and fully supplied throughout the course of your entire campaign.
Ship Attributes Cheat
Using this cheat you can modify the attributes of any ship in the game. To take advantage of it, go to your Starfleet Command II directory and navigate to Assets/Spec then find the file "Shiplist" and make a backup copy of the file. You can then open the file, using a spreadsheet program, such as Microsoft Excel, or a text editing program, such as WordPad or NotePad.
From this file you can alter almost any attribute of every ship, including hull strength, shield strength, weapons, acceleration, appearance and even the sizes of the ships' shuttle bays and boarding parties.
Hints
There are three elements that you need to be constantly aware of when you play Empires at War: positioning, timing and power management.
Positioning is vital as you make passes at your enemy. You always want to approach your enemy's weakest shield as you attack, and only present your strongest shield to the enemy, thus maximizing the damage dealt to your opponent while minimizing your opponent's ability to damage you.
Timing is essential in knowing when to attack. Fire your plasma torpedoes too soon and they may do very little damage by the time they reach your opponent. Engage your cloaking device too late and your opponent may be able to unleash a crippling attack when you don't have the full benefit of the cloak's damage reduction. Understand the rules of your faction's weapons so that you can use them to their greatest potentials. For instance, if you are playing as a Romulan, know how long it takes for your cloaking device to turn on and off and also understand at what ranges your plasma torpedoes are most effective.
All of your ship's systems, including weapons, shields, engines and even tractor beams, draw power from the same source, forcing you to prioritize certain systems as battles progress. Knowing this, don't rush in at the beginning of a battle to face your opponent. Instead, give your weapons time to charge and buffer your shields with leftover energy, and only then move to engage your foe. As the battle unfolds, only divert as much power to your engines as you need in order to maintain maneuverability, giving as much power as possible to shields and weapons.
