If you've already bought PlayStation 3 exclusive Starhawk, you've gotten more value for money than perhaps you've realized. Sony have announced that people who register their online passcode will get access to the original PS1 classic Warhawk which will, if nothing else, highlight just how far the series has come. As soon as you put in the pass, Warhawk will be added to your download list (although I can't imagine too many people will be jumping into it straight away).
The PlayStation game was famous for its 360 degree flight, its various weapon systems and its humousous cutscenes. It would later be revived with Warhawk for the PS3, an online title that in turn gave way to Starhawk. The PS1 Classic is in addition to the extra prizes if you took part in the beta and if you owned the online version of Warhawk.
Starhawk is out now in the US and at the end of the week here in the UK.
