ICYMI, this is the unreleased DOS conversion of Team17's little Amiga classic overhead racer Overdrive.
As opposed to the "official" DOS conversion, this one was developed by a small Italian team, it runs much smoother and features 4 opponents on the track, instead of 2.
The team allowed me to preserve it online, you can download it here: https://archive.org/details/Overdrive_Unreleased
