Conduit

A few decades ago I came across a Nintendo Wii game called the conduit. It was made by Sega for Nintendo. In my opinion it had the look an feel of the X box game called Halo but the Nintendo network was free. 

Basically you run around in first person perspective as if you were looking through a person's eyes and you would shoot or throw grenades at people. I remember there being six maps to choose from and at least 4 weapon sets. 

The network for that game is gone now, what a shame.
