A playable version existed before its cancellation. In January 2007, Matt Casamassina of IGN claimed he played a version of Halo for the Nintendo DS. On October 2, 2007 he demonstrated on-camera, and in-game footage of an early-development style version of Halo DS. The demonstrated work featured dual-wielding and a version of the Halo 2 map Zanzibar. Bungie employees later explained the Halo DS demo was in fact an unsolicited pitch that was never taken on.
- This game was joked about, but denied, by Matt Cassamassina of IGN
- There are no further plans to publish or release a Halo game on the Nintendo DS.
- The bottom screen was used mostly for the motion tracker but also had other uses, such as to tell you what weapons you had and your shield health.
