The Kickstarter campaign for Road Redemption, which takes its cues from 1990's Road Rash, was a chain-swinging success. Now the combative bike racer is available with an early access alpha for $40.
It's not yet come to Steam Early Access but having passed Greenlight it will be eventually. Road Redemption is still in the very early stages so expect the unexpected in glitches.
It can be pre-order for $18 but if you spend $40 then you, although a special edition for $70 comes with plenty of additional perks.
All three will reward a Steam key for when it releases on the digital platform.
