It seems reports of the delay of the PC version of Jonah Lomu's Rugby Challenge were somewhat exaggerated. While it's true that the retail PC version will come out on the 21st, a week later than the consoles on the 14th, this isn't the case for the Steam version. That's to be released alongside the cousins tomorrow. Why the delay? Developers Alternative Software explain to us the reason the boxed version comes later is because,
"We are just having to fly in the new PC retail box version from Australia."
You can see a trailer for the game below.
