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.

WARNING: There is a high amount of flashing lights in the intro and after defeating bosses (at 0:07, 0:41, 1:08, 1:49, 2:25, 2:46, 3:15, 4:01 and 4:22 in the encodes), viewer discretion is advised.
