As a kid, I used to think of this as the "Ooooooohhhhh!" game, because at the start of every level, all of the player characters say "Ooooooohhhhh!" in unison
The characters also say "Ooooooohhhhh!" when you level up. For maximum immersion while playing, be sure to also shout "Ooooooohhhhh!" out loud whenever this happens
I love these late 80's/early 90's cabinets with the oversized control areas that almost look and feel like a tabletop; it drives home the communal aspect of arcade games, while also giving a lot of real estate for cool artwork
After you beat Bebop and Rocksteady in the parking garage level and rescue April, she gives a kiss to the turtle that has the highest score up to that point. Michelangelo does a cool pose in the background, meanwhile
There's a single frame of animation where you can see the "generic turtle sprite" that's used for this cutscene; the colored headband is then "painted on" for the correct turtle. Movie magic, folks!
The deluxe 2-monitor/6-player cabinet is so huge. I remember thinking as a kid that the entire cabinet was "filled with computers", thus making this the most-power arcade game by several magnitudes in my local amusement park arcade
The music in the second level of the game features a dude saying "Ecks-ecks-ecks-ecks-X-MEN" over and over, punctuated by another dude saying "C'mon" occasionally
"Dead Angle" is brought to you by the same developer behind "Dynamite Duke", who, by this point, had cornered the market on "games starring a semi-or-fully-transparent protagonist"
Even more unrelated, in Brian De Palma's "The Untouchables", Al Capone is played by Robert De Niro. Famously, De Palma had Bob Hoskins on call to play Capone if De Niro couldn't fill the role. Looking back at De Niro as Capone in the film, though, he looks exactly like Bob Hoskins. They Hoskins-ified De Niro. Interesting
