The massively-multiplayer title will centre around adventurers exploring a planet and uncovering the secrets of an ancient alien civilisation through multiple gameplay styles.
The focus of Wildstar is to allow players to play how they want, with Explorer, Soldier, Scientist and Settler as confirmed path-types.
'Momentum Mechanics' will also respond to play actions, with new content, challenges and rewards emerging based on player progress.
NCsoft also revealed that Guild Wars 2 will also be playable at gamescom, showcasing all five character classes, customisation and underwater combat.
"WildStar and Guild Wars 2 showcase the innovation coming from NCsoft's development studios, paving the way for the next generation of video games and setting a high bar for the entertainment industry to follow," said executive vice-president Matt Turetzky.
"We are focused on delighting players by delivering fun, immersive experiences that rival traditional forms of entertainment through personal expression, best-in-class gameplay mechanics, and social engagement."
Wildstar will be available to play for all public attendees at gamescom from today, while a full release date has yet to be revealed.
