Your crew boards what looks like a salvage. Instead, you find a man who can barely speak, and then the ship starts showing you why he's the only one left alive. Roots Search doesn't waste time on exposition or false scares, it just presents the horror as fact and lets dread compound with each new discovery. This is the kind of '80s sci-fi horror that understands silence and implication do more damage than gore, and by the time you realize what's actually happening aboard the Green Planet, the claustrophobia has already won.
A deep space research vessel encounters the drifting wreckage of another ship: the Green Planet. Its sole survivor, Commander Buzz, is alive but barely coherent, unable to communicate what happened aboard his vessel. The research crew takes him in, hoping to learn his story and salvage what they can from the derelict craft. What they don't know is that Buzz isn't the only thing that made it aboard their ship. What begins as a rescue mission quickly transforms into a nightmare. Something from the Green Planet moves through the corridors of the research vessel, and it's far deadlier than any equipment failure or structural collapse. As crew members disappear one by one, paranoia spreads faster than whatever hunts them in the dark. Trust dissolves. Survival becomes the only priority. This is sci-fi horror stripped down to its core: isolation, uncertainty, and the realization that some salvage isn't worth the cost. Atmosphere hangs thick throughout this compact story, building dread with every passing minute. If you want claustrophobic tension that doesn't waste a frame, this OVA delivers exactly that.
