Dave Bautista, passionate about these games and self-proclaimed Marcus Fenix in the movie Gears of War, is a free download in all versions and a skin of Fenix itself in multiplayer mode. That is, it is not really a character added with particular features. But he has personality, since they recorded more than 700 lines of dialogue and put them into his performance to avoid strange sensations.
for anyone who wants to see how that skin is, I'll be playing Twitch with him. https://www.twitch.tv /canalbgv/
