Chuck Rock II: Son of Chuck is a slapstick side-scrolling platform video game developed and published by Core Design in 1993 for the Amiga, Amiga CD32, Sega Game Gear, Sega Mega-CD, Sega Master System, Sega Mega Drive/Genesis.
The story takes up a little while after the end of the first game. After Chuck Rock rescued his woman, Ophelia Rock, from the T-Rex bully Gary Gritter, Chuck and Ophelia had a son, named Chuck Junior. Chuck senior works in a factory, where he develops great skill at carving automobiles out of stone. A rival manufacturer becomes jealous of Chuck's abilities and kidnaps him, leaving it up to Junior to rescue his father.
Gameplay:
The gameplay is similar to the first game, but with some minor differences since the player controls Junior, rather than Chuck. This is a side-scrolling platform game with occasional rock-moving puzzles thrown in. Unlike Chuck, Junior carries a club that gives his attacks further reach.
