The DS game was probably the first FPS of the system, after Metroid Prime Hunters: First Hunt, the demo of the game (that came out much later) and it was a pretty fine job from n-Space, the studio that developed most FPS on Nintendo DS. They developed it the same year as Geist, one of the best Gamecube games I'd say.
Iirc it was the only game that ran on Ensata, the DS emulator of the Nitro SDK.
The game, both on home consoles and Nintendo DS, is pretty good, but the rail gun of the last levels, which kills you with a single shot thought the walls, was a pita.
