SEGA Announces Aliens: Infestation for Nintendo DS – A Side-scrolling Action Adventure Set in the ALIENS Expanded Universe

LONDON & SAN FRANCISCO (July 20th, 2011) – SEGA® Europe Ltd. and SEGA® of America, Inc. today announced Aliens: Infestation™ for Nintendo DS™, bringing the action-packed experience of the popular ALIENS™ film series to Nintendo’s best-selling handheld console in September 2011. Players will be able to recruit and play as 19 different marines, each with their own unique dialogue, and explore iconic environments including the Sulaco, the Derelict ship, and LV-426. Aliens: Infestation is an action-heavy side-scrolling exploration game and will be part of the ALIENS expanded universe.

Developed by WayForward in collaboration with Gearbox Software, Aliens: Infestation will pit players against the overwhelming Xenomorph hive using a vast selection of iconic weapons and tools from the series. Featuring character designs by popular comic artist Chris Bachalo and equipped with an upgrade and collectibles system, Aliens: Infestation will allow players to explore large-scale versions of some of the most fan-beloved environments of the iconic films.

“In contrast to our other Aliens title in the works at the moment, Aliens: Infestation delivers a game that focuses more on exploration of the expanded universe,” comments Gary Knight, Senior Vice President of Marketing, SEGA West. “WayForward really put all their passion into making Aliens: Infestation the definitive Aliens experience that you can fit in your pocket.”

Aliens: Infestation will be available September 2011 on Nintendo DS.
