If you're a fan of sci-fi action shooters, nine times out of ten you'll end up having to control one of many grizzled space veterans. There's no escaping it - you'll have to guide your hero through all manner of aliens, monsters or both if you want to see the day through victorious. Up until the sequel, of course.

But out of the many (admittedly white) protagonists, which space marine has been your favourite? More generally, what do you think about the 'space marine' genre? Is it positive, or rather derivative?

Below are an array of space marines. Take your pick, or if you've got a really obscure one, feel free to choose the 'other' button.

Doomguy, from Doom




Master Chief, from Halo



Shane Carpenter, from Haze

And presumably many other examples. Bonus points if you can get a space marine who isn't white male.
