Sling and Slingette are made of stretchy goo and can be pulled and released like a rubber band. To pass each stage, you must turn all of the white grab pegs green by slinging onto them one at a time. Breakaway pegs, spikes and even fire pits stand between you and the blue vortex exit, and every five levels you must face off against one of the fire monsters in order to continue.
Sling Fire is more of the same goo-flinging fun we've come to expect from the series. A few new grabs make an appearance in this game, including fire cannons and beetles, but just about everything else you've seen in Sling or Sling Jr. Regardless, Sling Fire is a polished and well-put-together game that will have you laughing and slinging for a very long time.
