Apocalyptic RP Ideas

Creep: An unknown toxic, highly corrosive sludge called the creep comes out of nowhere and decimates almost every race and world in the galaxy. One city remains, keeping the creep at bay with its anti creep arsenal, surrounding the city. The city holds 1 million citizens. Rebellions or wars sometimes take place within the city, some even utlize the creep as a weapon, shutting down anti creep weapons to a city district. Abominations may be created, beasts with no purpose but to destroy life, blah blah blah you get the idea.

Flooded World: Earth, or another planet, gets flooded with water somehow, form melting ice or a massive comet that melted or something. All life remains underwater, relying on life support, submarines, etc.... They can be cut off from civilization on other worlds, or be all that is left.

Zombies: You all know. Zombies take over the world, and they are their mutations rule. The several thousand remaining survivors have wars over what food and water and weapons remain. Survival is difficult, you get the idea.

Nuclear Apocalypse: You get the idea.

Ice Age: Uber uber ice age. Like, the atmosphere to a world gets several holes in it or something, and temperatures are half as cold as space. (-150 degrees fahrenheit or something)

Torn apart world: A world literally gets torn to pieces, and turns into something of an asteroid field, with what pieces of the planet are left connected by artificial means, all still contained in an atmosphere(s).

You get the idea.
Post your own if you want, and give me some feedback on my ideas.

I got an idea.

Termanator 4 Idea: Machines rule the world. What's left of the survivors fight for their survival against the evil machines.

parasitic beings take over the planet, mutating the population into extremely inteligent beings, somewhat like the flood they depend on a single "hive mind" and there is many forms. a few rag-tag groups of people, and citys stand. most the people who arent infected yet are immune to the virus/spores/creature that does the deed so their in a never ending war with the mutant horde.

i suppose this is somewhat like a zombies theme but o well

Ummm...
1) Locust and Gears of War, cept with Starcraft creep...
2) 2012/Day After Tomorrow
3) Zombies...
4) Nuclear Launch Detected (Irradiated Earth RP)
5) 2012/Day After Tomorrow
6) Armageddon when Bruce Willis' nuke failed (lol)

Here's mine i guess:

Last Stand
Unknown forces descend upon planet after planet, destroying each and leaving nothing but charred remains behind.
Several warring nations band together in an attempt to hold off the unknown forces
Give uber computer to comp, I'll help hold as well
Better yet, actually make a map for like 4-5 of us

Mutant Invasion:

A secret labratory's expirements escape and create havoc across the galaxy, feeding primarily on the sentient beings of each planet.

Unlike zombies, the mutants are sentient creatures, but do not have speech capabilities.

the mutants can kill just about anything, and are nearly invincible, save for specialized weaponry.

Weird idea, but it'll work.

Polluted World

The planet has been polluted to the point rainfall now brings death and destruction to where it once brought life and creation.
Ordinary water and rain is now filled with so much acid it can melt stone.
What's left of humanity is scattered, or in small groups clustered around what's left of safe, uncontaminated drinking water.
Safe water can be anywhere, just not out in the open.

I've got a new one...

New Ice Age

Over 65% of Earth has been frozen, billions have already died of the cold.
What's left of the survivors try and live off what they can find and create.
People cound fight over dwindling supplies, or move to more tropical, coastal areas.
