Mad Lab Defense: Tower Defense

A funny offline tower defense game: build absurd lab gadgets, mix 21 reactions and stop a gray army of bureaucrats.
Lead 5 heroes, plan your strategy and play the whole campaign without wifi.

The Ministry of Normal has banned all fun science. Its gray army of clerks, inspectors and filing-cabinet tanks is marching on Dr. Max Sprocket's backyard lab. Luckily, Max has gadgets. Lots of gadgets.
