A couple of weeks ago Ubisoft announced that anyone who completes the Trials of the Blood Dragon demo will get a free copy of the full version of the game. Now that post has been amended to include an end date for the promotion. Word is, "Update: This special demo will run through July 31" (thanks VG247). Here's a refresher on the game: "Spanning more than 30 missions, Trials of the Blood Dragon follows Slayter and Roxanne – the dirtbike-riding, cybernetically enhanced children of Rex Power Colt – on a global mission to battle alien-backed communists by using bikes, guns, tanks, jetpacks, grappling hooks, and more."
