Outcast is an action-adventure video game by Belgian developer Appeal and released by Infogrames for the PC in 1999. A Dreamcast port of the original was also planned, but was shelved when the PC version failed in the marketplace.
In 2007, the U.S. government successfully sends a probe to an alien world in a parallel universe. The probe starts transmitting video images of the world back to Earth. Then, just minutes into the mission, an alien life form discovers the probe and damages it, causing an unforeseen backlash of energy to create a black hole threatening Earth. After being briefed on the situation by his old friend Major Vernon, former U.S. Navy SEAL Cutter Slade is given the job of escorting three scientists (William Kauffmann, Anthony Xue and Marion Wolfe) on a mission to this alien world to recover the probe and close the black hole. Arriving in this alien world, Cutter is separated from the other scientists and is hailed by the natives as their messiah, the Ulukai.
Adelpha is a world that is parallel to our own, and it is here that the action of Outcast takes place.The main population are the Talans, basically the parallel version of human beings. Their technology seems very primitive compared to our own; one could say theirs is roughly equivalent to what would have been found in ancient China or medieval Europe. However, their energy-based weapons and intercontinental portals suggest that at one point they were much more advanced. Adelpha is broken up into several regions, which are hinted to be separated by large water masses. Transport between regions is ensured by gates known as Daokas, which allows its users to instantaneously teleport from one region to another.
The player controls Cutter Slade in the parallel dimension of Adelpha, which is split into regions. Cutter can talk to some NPCs to locate other NPCs of greater importance. Outcast uses a unique way to save games, integrated with the game world. At the start of the game, the player receives an object called a "Gaamsaav". He is instructed that the Gaamsaav is able to "capture his essence", so that it may later be restored. To save a game, the player equips the Gaamsaav and "squeezes" it, making it glow and emit a sound. The sound can be heard by enemies and they will investigate, so that the player must take the situation into account before saving a game. After a few seconds, the game pauses and a menu overlay appears.
