Serious Sam 3: BFE (2011)

Note that Serious Sam 3: BFE is more darker and adult than it's predecessors despite some humor thrown in.

The Witch Harpy, a in-game enemy, is disguised as a woman with bare breasts, but it's merely a tool to distract it's prey. Fortunately, mods can censor the nudity by adding clothing to the sensitive parts.
