Right. After playing a lot of Gears of Wars 3 and Repercussions, I've come with an idea like this one.
After many years of war, constant battles between the two sisters has occurred. Many of them were colossal. But in everyone of these battles, they caused entire cities to be destroyed or badly damaged. Years has passed and the sisters somehow have gone. Now, the two enemy factions, many of them just survivors, still fight each other (with less frequency, though.) On the lunar side, one squad attempts to go and find food and weapons supplies. However, with the sister's magic still present, many things has changed, such as some ponies, turning them into horrible, flesh eating, former-selves.
So? Anypony in?

So your creating a fallout equestria or armageddon type of scenario?

Not much like armageddon itself, but an after-armageddon scenery. And it's just an experimental labor (you know, just to see where it takes to).

2875901

Ehhh thats not really my style. I mean i like survival and all just not after apocalypse. Good idea anyway

2875840 sounds interesting, maybe flesh it out a bit more for us?

The team in question, maybe 4 or 5 ponies on it are sent from the lunar HQ to the neighbor city of Phillydelphia. Resources are low, not to mention the ammo and weapons. Phillydelphia, once a huge and busy city, is nothing but ashes. Magic traces have been found near of the city's center. As much as HQ wants to avoid that place, it is the only part which hasn't been explored.
Desperate, HQ sends a small squad under the code name of Eagle in order to explore and find food and any other possibles resources.
Once the squad is in there, they start to find many signs that points to recent battles. Short after that, they find a survivor who tells them to hide as fast as they can, due to the "infection" that is happening.
Eagle soon find what the survivor meant, when they get closer to the center area.
The massive amount of magic in the environment has caused that many survivors who have been exposed for a long time changed into a former version of themselves. These are ponies with and instinct to eat anything that they can find (many times, they even eat themselves).
Eagle must find a way to stop this infection.
There will be four or five available spots:
The captain.
The second-in-command to the captain.
An specialist.
One or two back-up soldiers.

Soooo, like STALKER: Clear Sky? But more pony?

2880981 And with cheap-ass pseudo-zombies.

I'd like to see you battling cheap-ass pseudo zombies when you don't have ammo or even a weapon. Remember: it's on a future when the world have been devastated by war. Original COs may be older. So, if you in, I'd like to recommend to create another CO.

2885078 I'm just saying that Pseudo-Zombies are the cheapest cop-outs in storytelling ever, especially in a post-apoc scenario. Heres why:
-- They're unoriginal,
--They're dumb, require no interaction with the PC's and their actions are predictable,
-- You can apply them to nearly any fic/RP, again, unoriginal and lazy
-- There are so many better and cooler options! Have us fight other survivors after the same resources, or face down Metro: 2033 style mutants or interdimensionally-ripped aliens a la Half Life!

Actually, if you read right the description, I said that after years of the war officially ending, NLR remnants and SE remnants still fight against each other, even when the world is in ashes.
One objective is to make a squad of the NLR to get in a forced alliance with some dudes from the SE in order to survive to a huge horde of cheap-ass pseudo zombies.

2897942 that would certainly make for some interesting storytelling, have you been in touch with some of the guys from the SE forums? All I'm saying is that perhaps instead of resorting to the above enemies, perhaps you could use something a bit more inventive, I'm not taking a #2 on your idea, it sounds good and you can count me in.

Which one do you like and who will be (your CO)?

2898126 I'll take 2nd-in, I'll be playing as my new OC on the Air Force RP, Obaskyr. I'll get a character log up in a day or so, when I've un-passed out from exhaustion
