If you were a gamer extraordinaire, then the elusive and highly sought-after Katana was yours to proudly display on your Master Chief back. Securing this ultimate boon wasn't easy. You had to get every achievement, forty-nine of them in fact, and while most of them were fairly easy to achieve, there was one or two that were extremely difficult.
Among these was the "Two For One" achievement: Score a Double Kill with a single spartan laser shot in a ranked free for all playlist (online).
This one ate my biscuits. It was impossible. I spent more time than I care to admit trying to achieve that bugger. Then, a friend of mine from work told me he had gotten it easily. By cheating.
Apparently, there were enough frustrated gamers out there struggling to achieve this elusive task that they formed an alliance and talked of their plans on a popular message board. If you reconfigured the language on your xbox so that you were able to join them in a match, then everyone playing could 'assist' everyone else by achieving the impossible.
I did this, got the Katana, but felt terrible about it afterwards. The victory tasted like ashes. So, in order to redeem myself and restore honor to the Halo universe and the Katana which it represented, I proudly present my legitimate (and extremely LUCKY) securing of the achievement: Two For One.
