WolfOlavo 3D is a mod for registered Wolfenstein. It was released in 2014.
The mod does not feature any new levels, but a new set of graphics. The protagonist is political Pundit Olavo de Carvalho, taking on a variety of Brazilian and other South American political left-wing personalities, including Lula da Silva and Nicolás Maduro of Venezuela.
Graphics were borrowed from Majik Monkee and Thomas Weiling though this was not mentioned mentioned - and some were unique to the mod. These include topless female soldiers and highly saturated textures.
Clearly the author's message was more of a political nature rather than a Wolfenstein mod, as such the Read Me is only available in Portuguese and the mod might not make a lot of sense to people not well versed in Brazilian or South American modern politics.
The became unavailable for some time after its release, most likely due to its subject matter.
