(PS1) Bokan to Ippatsu! Doronbo

Vertical shoot’em up published by Banpresto in 1996 for PS1 (and a year later on Saturn) and developed by Eleven, authors of the arcade vertical shoot’em up Mazinger Z.
Set in the Time Bokan series, the Doronjo team has to defeat different heroes from the series for a total of 8 stages.
At the beginning the player can choose a mech upon the six available (and other three can be unlocked through the game) with one rule, any mech can be used for two stages in a row cause due to repairs; through the game there can be found skulls which grant the player with a bigger mech with a powerful attack.
The game is quite enjoyable and reflects the comedy of the anime series, it was released only in Japan.
