8. Space Marine

If you watch the space marine trailer below, you might think I was crazy for including it amongst the sexiest ads, as the first person to be seen in the ad is a senior with a walking stick. But fear not, as he is followed by none other than renowned model and actress Tricia Helfer.

This Canadian beauty is no stranger to the video game world, as she has done plenty of voice work for games, including the Halo and Mass Effect series. And she definitely exudes sexiness in this trailer, wearing a blue dress that accentuates her curves. But even if models like Tricia Helfer are beyond your reach, you can still find solace in the fact that, according to the trailer, anyone can be a “space marine”…
