You play as bat Aero, who have to stop the mad scientist Edgar Ektor, who is trying to rid the world of amusement and fun. So you jump through the circus-style levels, using different kinds of machines such as catapults, cannons, bubble machines, platforms, etc., collecting various power-ups such as cheese, soda, keys, clocks, etc. and avoiding lethal obstacles.
In the sequel to Aero the Acro-Bat you have to defeat evil industrialist Edgar Ektor once again. He is back and again with bad ideas, so you - in the role of Aero - have to find and destroy him before he carries out his diabolical "Plan B". Like in the last installment, you have to jump, escape lethal obstacles and progress in time. This game features more moves for Aero, more mechanisms to use and more items to collect.
Single player takes the form of a "Story" mode divided into five episodes and fifteen linear levels. The player will face weak minions (which change based on the episode), plus occasional sub-bosses which will try to escape into town. The final level is devoted to a unique boss fight. Players use quirky weapons ranging from infinite yellow snowballs to cow launchers and toxic Terrance and Phillip dolls. Every weapon has a secondary fire, and players switch between the four main characters when they switch weapons - each of the four kids shares a single life bar because of this. The kids will comment on game actions as they occur, with heavier profanity censored with bleeps. The kids will get angrier (and fouler) as their health depletes, until they finally give up on saving the town and go home.
Having defeated the Campaigner, Turok throws the Chronocepter into a waiting volcano to destroy it. Unfortunately the blast awakens an even deadlier force - The Primagen. Once again a Turok is tasked with restoring peace to the land and stopping the Primagen from merging Earth with the nether world.
