Outcast

In the year 2007, a parallel universe is discovered by scientists. The U.S. government sends a probe to that universe and learns of the existence of an entire alien civilization there. However, an apparently hostile alien damages the probe, leading to the creation of a black hole threatening the very existence of our own world. Former U.S. Navy S.E.A.L. Cutter Slade is assigned to escort three scientists to the parallel universe in an attempt to repair the probe and avert the danger.

Outcast is a 3D third-person (with optional first-person view) action game with adventure elements. In search for five sacred relics, the protagonist travels through the five continents of Adelpha (plus one tutorial island). Each land has its own landscape (mountains, lakes, forests), populated areas, as well as dozens of minor problems - small quests that the hero is required to solve. Most Talans populating the world can be conversed with about a variety of topics. A large portion of the game consists of finding key characters and performing quests for them; some of these are optional, though most must be completed in an adventure-like linear fashion in order to advance the plot. Cutter is free to travel between the continents using special portals.
