In 1915 The Great War comes to a screeching halt as a massive rock from space smashes into Moscow, killing millions and destroying the Russian will to fight. Germany turns and manages to use its forces formerly devoted to fighting the Russians against the French and the British, securing a swift German win...and a supposed end to the war.
But then, in the ruins of Moscow, the asteroid has been excavated. It is found to be composed of a mineral completely unknown to the planet Earth...the mineral is named Moskite, after the city it had destroyed, and it is soon found to have amazing powers! Place it in a boiler and the steam that comes out is super efficient! A tiny bit of moskite turns a steam engine into a super device capable of outshining any gasoline driven or electric motor!
Germany and the rest of Europe is rather shocked when the Russian economy is suddenly boosted to amazing new heights by the astounding powers of Moskite. And then steam powered warmachines plow into Germany and the rest of Europe, securing a victory in a few weeks. The United States and Britain desperately seek for their own supplies of Moskite...and find it, in the bottom of the Gulf of Mexico, where an even larger asteroid smashed to Earth and brought about the end of the dinosaurs.
An uneasy silence falls about the world as Americans throw themselves into Moskite technologies with a wild abandon, manging to shake off a slight economic upset in the late 20s and early 30s.
Now, it is 1939. You are a brilliant German who has spent most of their adult life living under Red Russia's iron boot. You are one of the most capable German inventors, however, but you yern to work with Moskite...but only Russians or die-hard commies get to work with those!
And then you are approached by a seemingly innocuous organization called the National Socialist German Worker's party. However, under that name, this group secretly longs for German freedom and a return of the Kaiser. You are brought on board as part of a scheme to steal some Moskite from Berlin's moskite reactor. With that hunk of Moskite, it is hoped that you and other German scientists can work with American spies to create a Moskite Bomb, a weapon of unusual and terrifying power.
However, the plan goes south and the ring leader, a rather short man named Adolph, is shot dead by the guards at the reactor. You are shot in the back and are left for dead...
But you managed to keep a thumb sized bit of moskite on your body and when you crawl your way out of the dumpster the guards (who really didn't want to fill out the paperwork involved with killing someone on the job) tossed you in, you immediately set to getting out of the country. Which is hard, seeing as how the faces of all the members of the National Socialist German Worker's Party were all identified and the entire country is out looking for you...
But you have the moskite and your brain! It is not quite enough of the miraculous mineral to build the Moskite Bomb...but it is enough for you to create a small Steam Cell. The Steam Cell is a small cylinder that is capable of spewing an almost infinite amount of super heated steam in one of two directions. Armed with this, your intellect, a small pocket welding torch, and a helpful/beautiful Irish spy...you have to escape Germany, get to America, and do your best to battle the Red Russian Menace!
The gameplay would be a mostly liniar affair, with the real innovation being in STEAMPUNK, alternate history, and the invention system.
Essentially, you can attach ANYTHING to your Steam Cell (or SC for short). Put a vacume cleaner on it, weld it up right, and you can make an ultra-sucker, that can suck anything to you from any distance. Then attach a pressure gauge and you can switch the direction of the sucking...and be able to blow anything you want away from you!
Put a box of nails onto a funnel ontop of a reversed vacume cleaner, then add a telescope...and you have a long ranged nail gun sniper rifle.
Now, the SC has two sides. You can modify both, giving you a close ranged and long ranged weapon...or two long ranged weapons. Or a sucker on one side and a blower on the other, to make a gravity gun like device. Or...well...anything you want.
Your limitations would be your Steam Power and Water Supply. Water Supply is basically your ammo. Get more water at water fountains (slow) in water bottles (fast and renewable but you need to fill them at somewhere else) or from fire hydrents, or lakes and rivers...or...well, anywhere there is water to be found.
The Steam Power is essentially a complexity limiter. The more doobobbers you put onto your SC, the less Steam Power you have, as it has to be routed through more and more stuff. Now, finding more Moskite will help, as that will increase your Steam Power...but Moskite is very rare. So, if you have 2 super complex guns, they might not have enough Steam Power to fire quickly...you'd have to charge up the steam power using some kind of pressure chamber or something.
Anywho...that's my idea of an awesome game!
