Zero (0) A.D. is a free (open-source) real-time strategy (RTS) game featuring ancient warfare, a historically-based war and economy game that allows players to relive or rewrite the history of Western civilizations, focusing on the years between 500 B.C. and 500 A.D.
The project, developed by a group of volunteer, hobbyist game developers since 2001, is after state-of-the-art 3D graphics, detailed artwork, sound, and a flexible and powerful custom-built game engine. 0 A.D. is a celebration of game development and ancient history.
The current release features Hellenic factions such as Athens, Macedonia and Sparta; technologies, civilization phases, click-and-drag walls, healing and more!, Multiplayer networking (Peer to peer, no central server), A level editor (Atlas).
Athenians, Macedonians and Spartans will now replace the generic Hellenic faction. Each features some unique characteristics along with shared Hellenic units and buildings: Receiving significant naval bonuses, the Athenians are the rulers of the waves.
Special Buildings: Gymnaseion, Prytaneion (“Council Chamber”) and Theatron.
Macedonians have a wide selection of units and siege engines, for a combined arms approach.
Special buildings (in planning): Lighthouse and library.
The Spartans can’t build stone walls, but as their soldiers are top-notch, their men serve as their walls instead.
In 0 A.D., technologies come in mutually exclusive pairs: Within each pair, you can either research one tech or the other, but not both in the same game. As researching some technologies depends on having researched others, one should plan ahead carefully. (Importantly, for the meantime, all factions share an identical tech tree, but over the next few releases, different factions will get different tech trees, adding complexity and interest to the game.)
Healing units from their battle wounds is now possible by a priest conducting a ceremony with special chants within range. Priests can be trained at the Temple. The Iberians get a pre-built walled settlement as a bonus every game.
Please note: this is the alpha release – far from the finished playable version.
