PS3 owners clinging onto consoles running firmware earlier than 3.21 will do well to note that Rockstar’s Red Dead Redemption not only requires that particular system software to run, but handily includes it on the disk for easy installation, too.

Chances are there have been other games out since April 1st that required the OtherOS removing firmware update, but Redemption is likely to be one of the higher profile titles to do, and as far as wee know this isn’t stated on the box at all so consider this a notice if you’re still to pick up the game.

This means that if you want to play Red Dead Redemption and hold on to your OtherOS installation you’ll need to grab yourself another PlayStation 3.

The PlayStation Blog did warn PS3 users that this might happen in their post at the end of March – “Use of new features and improvements that are available on PS3 system software 3.21 or later” and it really was only a matter of time before the update became compulsory.
