Late 90s isometric sci-fi shooter like the Crusader games. Had the same sort of look, only the sprites were much bigger, or seemed that way back then. The characters you played as were robots/guys in power suits, each a primary colour. I want to say it was squad based, where you could switch guys.
Only other solid memory was that the demo level had this two story sci-fi building that you could enter, and the ground outside was kinda snowy.
Pretty vague, but does anyone have any idea what it might be?
Edit: Uh huh. Went to the Crusader: No Remorse page and, would you believe it? The game I was thinking of was listed as a similar title.
