File:Riberts.gif The Hairbuster Riberts is a playable unit in Metal Slug Attack. Compared to the Dai-Manji, another aerial unit with a suicide attack, the Hairbuster Riberts is the superior choice. It costs significantly less AP (500 vs 700), and glides towards the enemy when self-destructing (whereas the alien vessel simply falls straight down). This gliding property allows the Riberts to explode on less durable long-range units, often wiping out large groups in a single swoop.
