NOT REQUIRED FOR FOUR EMPIRES TO RUN. THIS IS MERELY A VISUAL ADD-ON. A graphic modification that will make Warcraft 3 more vivid and contrasted, as well...
Four Empires is a total conversion modification for Warcraft III: The Frozen Throne that turns the four vanilla races into different ones. The Universe in which the mod takes places is one of my own imagining and has nothing to do with the Warcraft universe.
The mod currently doesn't have any AIs, so you should play with friends on LAN (I cannot tell you to try Bnet since I don't know how if it will work, or even if Blizzard allows mods on Bnet). If you do not know how to do that, you should try Hamachi. Here is a guide for Windows 7 Wiretuts.com
Follow until step 11. It should be enough.
Humans are the HOLY EMPIRE
The Holy Empire formed relatively recently after the Emperor clawed his way out of the Hell to reclaim his throne after his assassination before he was crowned ruling monarch of what was only a Kingdom. No one knows how he escaped the Netherworld but after he returned to the land of the living he began conquering the neighbouring kingdoms and eventually conquered the entire central continent, creating the Holy Empire. The Emperor governs atop a throne of gold that rises like a pillar from a pit of boiling lava, damned arms reaching up the edifice trying, vainly, to pull the Emperor down back to Hell. He radiates light that is said to render people speechless with awe, and his powers can be witnessed throughout the entire Empire through the Imperial Channelers that form the backbone of his civilisation.
Orcs are the DOOM MARCH
Demons have always been able of travel to the land of the living, but always with heavy mystical restrictions that make the task extremely difficult. With the escape of the Emperor, however, the natural wards that protected the world have weakened considerably. Not fond of having such a powerful soul escape from their realm, the Demons have massed into a colossal army and opened portals to the lands of the Emperor, marching to reclaim their prize like an ominous wave of chaos and destruction.
Undead are the BLACK LEGION
Off to the west of the Holy Empire lies a group of large islands that are inhabited by vampires. Decades ago, when the vampires took over and ate the last of the humans, they began to starve, and while some journeyed east to the larger continent, most stayed behind trying to master their Bloodthirst... and the answer came to them from another world. In a parallel dimension, a race of enigmatic demigods called the Eidolons were contacted by some vampires who were seeking liberation from their vampirism. The Black Cult had been formed, and eventually, as more and more vampires fell into the worship of the Eidolons, it grew into the Black Legion. Now, most vampires of the world are part of the Legion, and those that defect or resist are branded Apostates and condemned to live out their Bloodthrist until their last breath.
Night Elves are the SYLVAN GUARDIANS
With the arrival of the Doom March the fey kind that inhabit the continent reeled from the sheer corruption that the Demon brought with them, and promptly reacted by calling to them the denizens of the wild. Their army is whimsical, mystical, and deadly, summoning forth ancient powers of the world to cast back the demonic influence back into the Netherworld.
Four Empires is played pretty much like any other warcraft 3 map, but it does have a few things that have been altered.
The Champion is what I call the Hero. In this mod you only have access to 1 Champion and must pick him/her/it at the very start of the game. All Champions begin with 2 passives that level up as they themselves level up (one is personal and the other is aura), and can learn 4 other hero skills. They are stronger than the taditional wc3 heroes which makes up for the fact that you can only have 1.
Once you pick your hero, you will notice that under you hero's icon is a deactivated mana-shield icon. This is where you obtain your secondary resource, Krin.
Initially, the mod only use gold for anything, but this proved to be quite boring and over simplistic, which is why I brought back the second resource, but changed it to fit with the theme of the map. Krin is my answer to replace lumber. You use it just like lumber, but you gather it differently. Krin is obtained by converting gold to Krin at a rate of 10 gold for 10 Krin per second. You can do this by clicking on the icon under your hero at the top-left corner of your screen, which will change the icon to an activated state (currently it's mana shield), indicating that Krin is actively being generated at the cost of gold. Click on it again to deactivate the gradual resource swap. The system works, but is quite inelegant so if you have any alternate solutions for it, I'm all ears :)
Your builders all summon buildings Undead style, and can switch between General Buildings and Defense Infrastructure modes. All the defense-oriented buildings are in this second mode, like walls and towers.
