I've said before and I'll say again that I'm at my happiest when the two worlds of Steampunk and gaming collide. After the widespread reports on the shelving of FuzzyEyes Steampunk game Edge of Twilight, the revelation that you can now Steampunk your Xbox 360 avatar went a little way to assuaging that disappointment and strengthening the increasing connection of the Steampunk aesthetic and mainstream gaming.
You can find the customisation kit via the Xbox dashboard if you click through the following tabs:
profile>customise avatar>marketplace>lifestyle collections>styles>steampunk.
Or you can browse the collection online here.
Below is an image depicting the clothing options available:
This one shows the final result of my avatar customisation:
Probably not the most Steampunk of ensembles I've ever seen but...I don't really do dresses, even on my avatars.
So if you have a few Microsoft points spare and your fancy a change for your Gamertag, don a pair of goggles before you start playing Bioshock 2 and Steampunk your avatar. It's guaranteed to make your play better (but not necessarily a better player).
The Steampunk avatar customisation was pointed out to me by @alan_hook. Thanks for brightening up my Sunday!
