Fire Shark, released in Japan as Same! Same! Same! (鮫！鮫！鮫！), is a 1989 arcade shoot-'em-up by Toaplan ported to the Sega Mega Drive in 1990. This is one of the few Mega Drive ports developed by Toaplan themselves.
Like many of the Mega Drive Toaplan ports, each regional release of the game contains multiple regional versions, of which European and US settings "Fire Shark" is slightly easier than Japan setting "鮫！鮫！鮫！".

and shoot; releases a typical "bomb" weapon. Powerups are a lot like Truxton; you have S icons for speedups (though it never gets as crazy as Truxton does), B icons to increase bomb stock, various #up icons to gain a number of extra lives, and thunderbolt icons to increase score. Finally, you have three different weapons: the cyan spreadshot (wide area), the green laser (focused area), and the red flame thrower (switches between focused and wide).
Most of the scoring in this game is cashing in bombs and thunderbolts at the end of each stage, so some pro dodging is required. After clearing the 10 stages, a harder version of the game will begin, and so on.
