Urusei Yatsura -Koi no Survival Birthday-

Based on Rumiko Takahashi's beloved manga, this adventure game was released by MicroCabin for the PC-8801 in 1987. After receiving a suspicious invitation to Ryoko Mendou's 15th birthday party, the player is dragged into a brutal "survival game" set within the sprawling Mendou mansion. By utilizing three floppy disks—a massive capacity for the era—the game presents the iconic cast through vibrant, full-color graphics. This title serves as a valuable artifact of 1980s character-based gaming, illustrating how manga properties were adapted for the early personal computer market.

The story begins when Ataru Moroboshi and his friends receive an invitation from Ryoko Mendou to attend her 15th birthday party at the Mendou estate. Expecting a fun celebration, the group travels to the mansion only to discover that the "party game" is actually a deadly survival challenge filled with bizarre traps. Playing as Ataru, you must navigate the mansion, overcome various obstacles, and survive the night to make it out alive.
