Terror of the Stratus, known in Japan as Senritsu no Stratus,[a] is an action video game developed by Nude Maker and published by Konami for the PlayStation Portable.

In "extermination mode", the game plays much like a 3D third-person shooter, while in "defense mode", the game plays like a 2D sidescroller.

[4][1] It was announced to be made by developer Nude Maker, who had previously developed Infinite Space with PlatinumGames, and Steel Battalion prior to that.

[6] The game was released digitally on the PlayStation Network, and physically at retail.

The retail version exclusively came with a sixteen-page artbook by character designer Katsumi Enami.
