I’m not ashamed of my pile of shame. Will add the game to my library. Thanks.

This game has a few technical issues. Widescreen is broken by default and the maximum horizontal resolution is limited:

There are also stability issues, especially on modern hardware. It’s not a particularly great game anyway, not even by the standards of AA games from the 360 era. I would only recommend it to die-hard fans of Warframe who want to see some early versions of assets and designs they are used to. IIRC, some assets are even identical. At least it’s very short.
