Civilization Call To Power

Activision released Civilization: Call to Power as a knockoff from Civilization.

One of the most noticeable features is that the timeline of the game does not end in 21st century, but rather goes to the far future.

Call to Power

There are five epochs in this game: Ancient Age, Renaissance, Modern Age, Genetic Age and Diamond Age. In the game, space colony and sea colony becomes a reality with appropriate technology advance (available in Genetic Age).

Terrain Features

Similar to Civilization II, the game uses an isometic view, although each tile is actually two separate tiles: the space level on top of a "terrestrial" level. Players can toggle between "Earth view" and "space view". All land and naval units are exculsively terrestrial, although most land units can be launched into space inside a cargo pod by a rail launcher in cities or via a space plane.

Space fighters and space planes can freely travel in space and in the atmosphere. While the SWARM warrior can survive in space as well as the earth, it cannot launch themselves into space. There are also some units that exist in space exclusively (i.e. cannot make a re-entry into the atmosphere).

Space produces no resources as it is a vast void. However, once a space colony is built, players can build food pods and assembly bays to produce resources for the colony.

"Water tiles" are also divided into several types, once submarines are available the type of tile in oceans can be seen (e.g. continental shelf, deep sea trench, rift, etc). Once sea colonies are discovered, undersea tunnels can be built to link to other sea colonies and dry land. Fisheries and undersea mines can also be built to produce resources.

Pollution

If pollution is left unchecked, eventually the game will give a warning that global disasters will occur. One of them is global warming. The game informs the player that "ice caps have melted" and sea levels have risen. Tiles affected are turned into either coast or shallow water, and cities on such tiles are destroyed.

Another effect is the destruction of ozone layer. When this occurs, a massive amount of land will turn into "dead tiles", which produces no resources.

Victory Condition

Apart from conquering all opponents, players can achieve victory by completing the Alien Life Project, which it is triggered by the "wormhole sensor" wonder. After a wormhole probe is sent through the wormhole, an alien life lab and a series of upgrades must be built to achieve victory.
