Autobots, transform and roll out!
Transformers: Convoy no Nazo (トランスフォーマー コンボイの謎) is about the Autobot Ultra Magnus cruising a very frustrating and difficult journey to discover who killed Optimus Prime. No, I'm serious.
Angry Video Game Nerd covered this game in 2009. Quoting adelikat:
As he describes in the video, this game notoriously difficult to play. Poor hit detection, 1 hit and you are dead, awkward controls, and very little in the way of power-ups make this game frustrating for the average player.
Note: There are some moments in this game that consist of heavy flashing lights, viewer discretion is advised.
