Steam had its "summer" sale not long ago, but hopefully you have a few dollars left to spare for the excellent open-world shooter Just Cause 2, which is currently a measly $US5 on the digital distribution service for the rest of the weekend.
All of the game's downloadable content is also on-sale, with prices ranging from $US0.24 to $US0.49. If you're keen on nabbing the official strategy guide from Prima, that's also 75 per cent off, but I imagine most can manage without it.
There was a similar sale back in February, so if you missed out then, here's your chance.
