Prelude Revision Phase: Small Arms
Proposal: Vent Rifle MK. II-A
Proposed as an alternative to the 'Vent Rifle MK. II' concept put forth by some of our engineers. The problem was brought up that utilizing Natural Gas to fuel the boiler would likely require dedicated facilities for harvesting it, thus taking up space we could instead use to harvest Metal, Wood, and Coal. Therefor, the MK. II-A(for Alternative) was made.
The primary difference between the two models, is that the II-A works off Wood gas, a type of gas made by putting wood(or charcoal) through high temperatures without actually burning them, put simply at least. Due to using gasses rather than solid coal, this has decreased the boilers size and somewhat lowered the charge time. The design does still contain one of the other modifications of the original MK. II however, that being the secondary regulator, allowing two 'charges' worth of steam to be stored for later firing.
Difficulty: Very Hard [-2]
Result: 6+6-2 [10] = Superior
The new and improved Vent Rifle MK.II-A, though somewhat utilitarian in name, was certainly an improvement on the original design. By using wood gas as a means of powering the boiler, the whole mechanism was made significantly more compact. Additionally, the inclusion of a secondary pressure regulator allowed the device to store up multiple, weaker charges simultaneously. Though it still took the full three minutes to gather enough pressure for long-distance shots, the same amount of pressure could be split between two short-to-medium range shots in quick succession. Overall, however, the charge time of the device has been significantly reduced, with very close-range shots taking only around 5 seconds to prepare.
It is now the Design PhaseAfter we repelled the initial attack on the colony, we had a brief period of respite where we were able to rebuild the colony into a livable state. Though we lost many to the frost before the central steam core was brought back online, and even more to small bands of straggling Jarnskeggi, we managed to build up a ramshackle defense and started sending out scouts to ascertain the raiders' movements. But for two months, there was a relative peace. Soldiers equipped with the newly upgraded Vent Rifle laid waste to the bandits still foolish enough to come after us in small groups, and we thought we were safe.
Then, a small detachment of scouts returned to Morecaz with a dire warning. A warband of Jarnskeggi were coming directly for us, armed with strange armaments and machinery never before seen. Firearms capable of rending a man asunder at close range similar to our Vent Rifles, tubes that sprayed liquid fire out to a range of 20 meters, and most worrying of all, an armor-plated vehicle trundling along on treads, impervious to our weaponry.
You are charged with designing an artillery unit. It is unknown where these bandits acquired this strange technology, nor how they were able to design it despite previously being equipped only with pre-frost era weaponry.
Colony Train: A thirteen-car steam locomotive capable of transporting upwards of 100 civilian passengers safely to a destination. Circumvents the need for an already existing track by laying out track in front of itself during the night, and travelling very slowly during the day.
Sheltered Outposts: A network of underground resource caches and repair equipment laid at fixed intervals along the train tracks. Staffed with a skeleton crew of engineers, scouts, and medics capable of dealing with a large variety of minor issues.
Vent Rifle: A steam-powered rifle based off of scavenged space heater designs. Uses high-pressure bursts of steam to propel 15mm ammunition at a wide variety of distances. Takes between 15 seconds to 3 minutes to recharge between shots, depending on the desired distance to the target. Produces an ear-splitting bang with each shot.
Vent Rifle MK.2-A: A version of the Vent Rifle that uses wood gas instead of coal to power the back-mounted boiler, making it much more compact than the original design. Also includes a secondary regulator that can be used to split built-up pressure into a two shot burst, though each of these shots hold significantly less power behind them.
