Deep Space Waifu is a series of Shoot 'em Up games developed by Neko Climax Studios. All of the games feature the player taking on the role of Bear-King, a bear-headed motorcycle pilot trying to get dates with women by shooting all of their clothes off.
The original game was released on Steam May 30, 2017, and currently features 13 stages, with some replaced or removed in updates to better fit within the distributor's terms of service. It also originally lacked a plot, but now includes short sequences of Bear-King trying to find a date by taking on a variety of jobs. A DLC expansion, ACADEMY, was released on September 15, 2017, and added an additional seven stages, each with a unique sports-themed boss. Since then, there have been multiple full sequels:
- JUSTICE, released on November 29, 2017, focusing on catching criminals with flat chests.
- FANTASY, released on July 31, 2018, focusing on girls of various fantasy classes.
- NEKOMIMI, released on December 18, 2018, focusing on Cat Girls.
- WORLD, released on April 24, 2019, focusing on girls from a variety of Earth cultures.
