Ninja Kiwi is a game developer best known for the Bloons tower-defense series and the SAS: Zombie Assault franchise. Founded by brothers Chris and Stephen Harris, the studio established itself with Flash-era hits and transitioned successfully to mobile and desktop platforms. Their portfolio includes long-running entries such as Bloons TD 5 and Bloons TD 6, plus competitive spin-offs Bloons TD Battles and Battles 2, which helped define their presence in strategy and multiplayer mobile gaming.
Across multiple platforms—Android, iOS, Steam and web—Ninja Kiwi has built a reputation for iterative game design, frequent updates, and community engagement. Bloons TD 6 in particular has reached substantial download and revenue milestones and remains a staple for tower-defense players. SAS: Zombie Assault 4 showcases the studio’s range, offering top-down action that contrasts with the tactical pace of Bloons.

The company combines a small-studio culture with sustained commercial success, keeping older titles active while developing new features and competitive modes. Their work demonstrates an emphasis on gameplay depth, post-launch content, and accessibility for new players, which explains why several of their games have stayed in active rotation among mobile and PC gamers for years.
