Empires And Allies ran on a heavily modified version of the CityVille engine (which is, in turn, a modified Farmville Engine). The game is focused around resouce gathering in order to buy units for use in combat, integrated with social interaction between the user's friends on Facebook. The game's notable depth when compared to other previous Zynga games can be attributed to the fact that it was developed by former Electronic Arts developers. The game had its run on Facebook ended on June 17th 2013.
Wrath of The Raven Storyline
After suffering an air raid that nearly decimated your peaceful island, You must lead your forces against the Dark Alliance, headed by the Raven, which seek to destroy your empire and take over Earth. Each of the Regions of your empire have been captured by a member of the Dark Alliance, and must be defeated before the islands in the area can be liberated.
Campaign Mastery was introduced, which allowed players to rebattle the enemy COs up to 3 times to earn mastery tokens, which allowed them to unlock golden versions of the villian units.
A second campaign, Molten Terror, was announced, starting at a medium difficulty.
The game is divided into an overworld where resources and unit production is managed, and a battle mode which can pit up to 5 vs 5 battles.
in the overworld, the player is given a map with limited range of movement. the space available to develop in can be increased by buying expansions. within this space, the player must focus on gathering eight different resources; Money, Oil, Wood, Gold, Aluminum, Copper, Iron and Uranium. all of these resources are needed to build and train units, and construct bulidings. As of November 8 2011, a Decoration Bonus was introduced, giving bonus resources to buildings placed near decorations. there is also a population limit, which can be raised by the construction of Government buildings. Military buildings can also be constructed to create three different types of forces: the Army, the Navy and the Air Force.
the player is able to interact with other facebook friends' empires, either helping them improve by preforming tasks for them, such as collecting resources, speeding build times, and repelling other invading players. also, the player can choose to invade a friend's empire to steal their resources. however, this is done at the risk of the player themselves being invaded.
There is also an honor system built into the player's interactions with friends. the player earns Red hearts for good actions to his neighbour, and Black hearts for conducting invasions.
The game also has a Player Vs Player mode that allows them to invade empires of random facebook users not on their friend list, and can win prizes after every battle. the player also earns black hearts for invading.
Campaign Mastery was later introduced to allow for re-battling of defeated enemies in the campaign for an increased challenge and the ability to gain Mastery Tokens.
in fighting, the units are split into 3 types, Naval, Aerial and Ground forces. these are further subdivided into a weakness triangle, with each unit having a rock/paper/scissors effect on each other.
overall, there are nine different types of units, each with a strength and weakness across all factions. The units which a specific type is strong against is written in red.
|Army Faction||Type 1||Type 2||Type 3|
Each unit type has units of increasing tiers of strength (eg. Grunt Soldiers are stronger than Cadet Soldiers), but each unit can be upgraded when a research faciltity for each faction is built.
The Titan Class was introduced on 2nd December, 2011, and is only available as an opposing class. They are segmented Mechas with Arms, feet and a Body of variable health. the arms are weak to Aircraft Carriers, Fighters and Tanks. The body is weak to Submarine Gunboats, Soldiers and Bombers.
Prototype units were introduced on Sep 20, 2011. these units have a secondary ability in battle, and run on canisters of Chemical Z. These units have no affinity for attacks, so they have no strengths or weaknesses.

Survival mode was introduced on October 6 2011. This mode allows you to select up to five units to fight off endless waves of enemies (akin to Horde mode/Zombie mode). after surviving each wave, you are awarded with different items, including resources, energy and special units. the more waves survived, the stronger the opponents, and the more rewards you receive for surviving. however, your units do not recover from damage, and will be lost if destroyed. also, you are not able to call on allies for help, but you are able to use powerups. you can give up any time by surrendering, which has no penalty.
on November 12 2011, an alternate Aerial mode was introduced, making the opponents only flying units, and changes the rewards.
Survival Mode is enabled when the war room is built.
