Want to win your very own Portal Gun? It's your last chance - the competition closes tonight, August 31st, Adelaide time.
But there's still a few hours left, so if you're up for a little social networking and a little creativity, this life-sized piece of Aperture Science technology could be yours, thanks to Gametraders, alongside a copy of Portal 2 for PC and Mac thanks to EA Australia!
There are only 5,000 of these Portal Gun replicas in the wild - they're the same as Chell uses in both Portal and Portal 2. Beware of imitations, this one lights up both orange and blue and makes all the appropriate noises. (The only thing it doesn't do is mess around with physics, but... maybe one day, right?)
Good luck, and be quick - you've only got a few hours left!
