WorldShift is a science fiction real-time strategy video game developed by Black Sea Studios and released in 2008.
WorldShift is set thousands of years after those events, when the human civilization is no more than just a fading myth.
The rest of the Earth is populated by what is known to be the Tribes, successors of the early humans that were affected by the Plague, and the Cult, a mysterious alien race with unknown origins.
[1] In WorldShift, there are no technology trees featuring hundreds of upgrades; instead, WorldShift allows the players to discover and acquire a vast number of items and powerful relics that they can use to freely change their gameplay and preferred tactics and to attack their enemies.
[1] Many units in WorldShift have power which the player can spend to perform special actions such as spells, healing, or stronger attacks.
