My recent healthy obsession with Tom Clancy's Rainbow Six: Vegas for the Xbox 360 has lead me to the largest achievement in the game. Rainbow Six Legend. Worth 100g, and although that may be quite a lot, it should be just a little more, say, 50g more. You have to complete the single player campaign on Realistic difficulty setting. It's hard.

Although, it's not actually that realistic. Your teammates are still dumb as anything, and the terrorists you're fighting have insanely good aim. Now, some of them are mercenaries, paid to do their job, but some are said to be people picked up to fight for the cause. They shouldn't have insanely good aim, they've probably never touched a firearm before in their virtual lives.

Now only three more achievements left. Time for me to take a deep breath and carry on killin'.

Thanks for reading, GameSpotters.
