I am doing a case study on early game promotional/advertising artwork, and the attached image is from a German advert for Tiberian Sun from 1999.

The closest match I can find is Maximus BT, but the a few letters are noticeably different once i overlay the type on the image. the letter R is the obvious one. Perhaps they used a older revision of Maximus BT?

I appreciate any help you can provide.

Try Fontbank's Maverick (1990/1991). A year later copied by Southern Software as Levelor Display Caps SSi.

You sir, are a absolute gentleman! Levelor Display Caps SSi is a a perfect match!

A match, not a perfect match. Compare the S of the Maverick and the Levelor Display Caps with the S in your sample and the Ü is missing in both.
