Alien Syndrome

Developer: Sega

Alien Syndrome on PSP revives Sega's arcade classic as a frantic top-down run-and-gun experience built for short, deadly missions. Players clear creature-infested corridors, rescue hostages, and haul them to extraction while juggling weapon pickups, explosives, and tense boss encounters. The portable remake keeps the arcade pacing with cooperative local play, permadeath-ish penalties, and bite-sized levels that encourage replay to improve scores and strategies. It's a nostalgic, fast-paced shooter that rewards map memorization and quick reflexes, delivering challenge and bite-sized tension ideal for on-the-go sessions or couch co-op with friends.
