I love zombie video games. A few years ago, for Wii, my brother and I got a game called House of the Dead: Overkill. This game was set up to play like a grind house movie with each new level being a new title with a trailer. What made this game more interesting (and overall entertaining) was the two main characters that we had to play. The first character is Agent G. Stereotypical white male who keeps most of his information "classified." He has several awkward moments with the other character, Detective Isaac Washington. Washington is an African American hard-ass cop who is always sputtering some profanity about what is going on. These two characters give off a hilarious banter between the highly slanged tone of Washington and the awkwardly-trying-to-match tone of G. Their clothes also depict their character types- G wears a business suit while Washington wears a t-shirt and jeans.
Another character that is added to the story is Varla Guns who is over-sexualized through the clothes that the animators has put her in and even the "camera" angles that are used with her. Specifically, she wears a mini skirt that is slit up the side, an extremely low-cut shirt, and overall looks like a typical suicide girl. The two male characters continually try to offer their assistance to her, but she ends up saving them in some way.
Keeping in mind that this game is supposed to play off of grind house films, makes it a little easier to accept the over exaggerated characters. Besides, you shouldn't be getting too offended by a video game.
