Arma II - 50% off weekend @ steam
 

for anyone with £12.49 to spare, its on steam at a special price

thats probably +VAT, I bought Garry's Mod off steam for £9.99 and got charged something like 12.99 unless I was ripped off..lol.

But still a great offer Though I have only loaded it up 3 times since buying it when it was released.
