Thankfully the heroic gene obviously runs in the family, so Chuck Jr. sets out tspoo save his father. So begins an adventure that takes the player through numerous side scrolling platform filled levels that are crowded with dinosaurs and quite frankly awful puns.
There feels like dozens of layers of parallax scrolling going on behind this charming main character sprites which gives the game impressive visual depth. There's far more variety of level locales too, and you see Junior scaling a tree that's slowly sinking into fire and venturing through never popular slippy slidey ice worlds. 'Chuck Rock 2' is also filled with quite a lot of subtle flourishes that just improve the overall look. From a hazy shimming background during the Lively Lava stage, to busy foregrounds seen in the butterfly grove section.
It’s a rather stylish and attractive end result. "The bosses are the most impressive I've ever seen" Dyson claimed in her review. "The bosses in 'Chuck [Rock] 1' were very big and pretty but they were basically just large sprites with minimal animation that glided and twitched in a not particularly special manner. In 'Chuck [Rock] 2' they really seem alive - different bits of their bodies move at different times and more or less the entire bodies are animated in some way."
There are also various mini games between levels which are far better than the typical fare that pads out 16bit games. "Usually these are pretty second rate affairs that seem to have been added because there was some space on the disk" said Amiga Power, reviewing the identical home computer version of 'Chuck Rock 2'. "These [mini games] are actually quite good. Not good enough to stand on their own, that would be too much to expect, but they perform the task required of them - to provide a bit more variety." Other level specific quirks have been done dozens of times in other games, but at least in 'Chuck Rock 2' they also break up the monotony of walking from the right of the screen to the left.
