The Colony (New Rp Idea)

Year:2095
Earth has been ravaged by war, famine, pollution, and poverty. In a final effort to give humanity a fresh start, the U.N. launches humanity's first starship. Ten thousand crew and colonist, with nothing to signify their country of origin, are placed in cryogenic sleep. Their destination is the planet named "Work in Progress" which orbits the Alpha Centauri system.

2128 8 days before planetfall
A Core malfunction has awakened the crew prematurely. As they attempt to repair it they find, to their horror, that a series of messages have been left for them by Earth saying that the super volcano underneath Yellowstone has exploded. The last recorded message was made 10 years ago while they were in cryogenic sleep.

7 days before planetfall
As repairs come underway, the captain of the mission is attacked and killed by an unknown assiliant. Panic and confusion follow. A few leaders are able to restore order, at the cost of the mission. They are now aligned not by nationallity, but by idelology.

Planetfall
The colony pods are boarded by the new factions and launched. The neglected starship breaks up as it hits the atmosphere and scatters supply pods all over the planet. Anyone left onboard is instantly vaporised.

The Planet
Size: 1.3023 times bigger than Earth
Atmosphere: Mainly CO2 and N2 with little to no O2
Info: The planet is deadly outside the habitation domes which humanity shall inhabit. The air isn't right for humans yet but the soil quality is super rich, so plants and trees will grow like their on steroids. It seems there is this fungus that grows everywhere, and spawns strange semi-sentient worm like creatures which will paralyze anyone nearby with psionic terror. They will then crawl and dig their way to the person's brain where they will implant their ravenous larva. There are also other strange semi-sentient lifeforms which shall be revealed as you discover them.

List for things needed for this Rp idea
Advance native lifeforms that can survive in little O2 atmospheres
Several Factions-
One which are survivalist/militarstic
One which don't wish for the event that unfolded on earth to repeat on the new planet (treehuggers)
One which are captialist bastards
One which is still trying to stick to the original mission
One which has the label "made in China" on it (commuist like faction which focuses on the workers)

Currency in this shall be Energy Credits (EC). Energy Credits can be created from excess power being produced and stored.

Let me how you all think about this idea so far and if you want you can also suggest somethings for the idea.
