Outcast is a 1999 third-person action-adventure RPG where you play as Cutter Slade, sent to the alien world of Adelpha to repair a probe threatening Earth. Gameplay centers on exploring five diverse continents, conversing with the native Talan, and completing quests to advance the plot. You utilize six futuristic weapons, craft ammo, and employ stealth, while movement is highly versatile—allowing climbing, swimming, and riding local fauna. The core loop involves balancing the main objective of finding five sacred relics against the world's internal conflicts. This title has received both a remake and a remaster.
The primary gameplay loop revolves around extensive exploration, quest resolution, and tactical combat across the five distinct continents of Adelpha, plus a starting tutorial area. Travel between these geographically varied lands—which include mountains, lakes, and forests—is managed via special portals. A significant component of the experience involves engaging with the local population; many of the native Talans can be conversed with about various subjects. Advancing the central plot requires completing a sequence of interconnected, adventure-style objectives, though some side quests are available.
Action sequences feature futuristic weaponry, providing the player with six distinct firearm options, such as a railgun. Ammunition management is integral, as supplies must be scavenged throughout the environment or synthesized by combining collected items. The aiming system incorporates laser sights to assist with target acquisition. Beyond direct confrontation, players can utilize stealth to silently subdue opponents. Furthermore, tactical gadgets, like a holo-decoy, are available to manipulate combat situations in the player's favor.
The game emphasizes comprehensive player mobility within its open-ended world design. The protagonist, Cutter Slade, possesses an extensive range of physical capabilities, including the ability to jump, climb, swim, dive, and crawl across varied terrain. For rapid movement across the large distances separating objectives, players can tame and ride a local fauna known as the Twon-Ha. This combination of deep social interaction and varied movement options defines the exploration experience.
The narrative is initiated by the discovery of a parallel universe by Earth scientists in 2007. When a probe sent to this world is damaged by an unknown hostile entity, the resulting instability creates a black hole that endangers Earth. Cutter Slade is deployed as an escort for the scientists to fix the probe. Upon being separated, he is drawn into Adelpha's internal strife. He is identified as the Ulukai, a figure from prophecy, and must retrieve five sacred relics to overthrow the antagonist, Faé Rhan, while simultaneously attempting to locate the missing scientists and secure Earth's safety.
This title was first released for PC (Microsoft Windows) in 1999. It is categorized as a Main Game and does not feature any associated downloadable content (DLCs) or expansions. The game has since received updates in the form of a remake and a remaster.
