PlayDevil has posted a review of the 'Summer Of Arcade' title "Trials HD".
Here's a snip:
"The actual trials bikes within the game are all represented well and do differ well as you upgrade, infact I would go as far to say that they are as good as many motorcycles in several full retail games. In addition the rider animations are pretty spot on and the over the top responses to crashes are very well done and add a touch of humour to proceedings."
They also offer a FREE XBLA code to the person who write a comment in the review, answering a very simple question.
