This month Microsoft are giving away Chariot (same as last month) and PowerStar Golf in Aus as part of Games with Gold.
However, in the US & UK they're giving away Volgarr the Viking instead of golf. It's very easy to get all 3 here in AUS.
for Volgarr the Viking do the following; On your xbox, go to your settings, region/language settings, and change your region to US. restart console. Go to store and search for Volgarr the Viking. download it for free (don't need any US details like credit card etc, coz its free! :)) now change your region back to Austraila, restart console, everything is back to normal and Volgarr the Viking will play normally even in AUS region.
For Powerstar Golf and Chariot it's the same except you simply do it from the AUS store.
Enjoy!
If anyone can figure out how we are meant to get Powerstar Golf for free (when you go to the store page it shows $26.95, yes I am logged in) that would be great :)
