It's 1897, and for the last five years Baron Battenberg's Steam powered war machines have ravaged Europe. Led by Great Britain, a handful of countries set out to stop the Baron. A tiny airship arrives at its destination, carrying Britain's greatest spy, explorer and fighter, Dirk Valentine. It's your job to fight off the Baron's army of soldiers and steampunk machines as you create your own platforms using Dirk's handy chain gun.
The chain gun is both your main weapon and a useful tool in this game. Not only does it dispatch enemies and collect medals, it also creates platforms that can snake across ledges. When standing on a brown-topped platform, fire the chain gun at another unarmored piece of ground. The chain will form a bridge between you and the other platform. If it bounces and hits other unarmored platforms, your bridge will continue and build up to three nodes. Later in the game it can perform a few more tricks, such as stalling platforms or zap through teleporters to take out enemies from afar.
