About Ninja Kiwi Archive
Ninja Kiwi Archive bundles more than 60 classic Flash titles from the Ninja Kiwi website into a single Windows‑only package. Each game is stored exactly as it appeared online, preserving graphics, sound, and code after browsers stopped supporting Flash.
The collection includes early versions of series such as Bloons TD 5, Bloons Monkey City, Bloons TD Battles and SAS: Zombie Assault 4, plus many hidden gems from over fourteen years of development.

Game Collection
The archive offers a curated set of 60+ classic web games, all kept in a “time capsule” format. Every title is presented exactly as it was on the original Ninja Kiwi site, with no alterations to graphics or code.
Because the games are preserved in their original Flash state, players can experience the forerunners to later releases and directly compare early design choices with modern iterations.
- Browse titles by genre to discover unfamiliar classics.
- Observe visual or mechanical differences when playing early versions alongside their sequels.

The archive offers the best single and multiplayer Flash game experiences, with PvP, online PvP, co-op, and online co-op among its listed features. Modes include PvP, online PvP, co‑op, and online co‑op, preserving the original multiplayer experience.
These modes function within the original Flash implementations, so the balance and rules are identical to the web versions. No additional modifications are applied to the gameplay.
