Okay, this is a Role-play that came to me in my sleep during a nightmare and dream cross-over, and it's a Dark Survival Horror Team Based Role-play. (VERY Team-based.)
I'm going to start off with the 'classes' in the Role-play I have planned, The Classes are pretty much fixed, though you have SOME freedom over the weapons AND Armor. So here goes:
Soldier/Veteran: The troops who have the most experience and were drafted from the Military in order to fight against this new threat that has presented itself. Soldiers are known for being almost indomitable in terms of their willpower and training. They use Assault Rifles and Shotguns, also carrying grenades to deal with any armor they come across. Soldiers have a small range of 'abilities' unique to them, they have been trained to channel their adrenaline into a concentrated Fight only reaction, giving a boost to their accuracy and resiliency to damage. Their armor also contains a special group of nano-machines that boost armor layers, allowing them to take a few more hits before any damage reaches them.

Machinist: The Machinists are troops who were taken from the engineering sectors of work and trained for combat, while a little fragile they can make some impressive constructs from just scrap. Known for their somewhat high intelligence and work ethic, they make sure everyone is happy with the constructs before making them. Equipped with Sub-Machine guns and Pistols for their weapons. The Machinists are able to construct turrets and pillboxes from almost nothing aside from bare essentials, they are also in charge of keeping vehicles running by any means necessary. Machinists can also create riot shields that the others can use, though sturdy they are quite cumbersome to provide adequate protection.

Survivor: The Survivors were ordinary civilians that survived an encounter with the new enemy and somehow fought back, most of them choosing to fight from a safe distance knowing what can happen when they're at close range, choosing to act as Recon and long range fire support. Survivors also act as combat medics, making them highly valuable on the field of battle. they wield Sniper Rifles and Machine Pistols for self defense should they get in close range combat. Survivor's are able to use Stim-packs and Medpacks to aid their allies, Stim-packs providing a immediate effect in recovery that allow for soldiers to get back into combat, but they won't mend serious wounds. Med-Packs allow for them to treat more serious wounds, but they must have time to treat the wounds. Survivors also carry Marker lights that allow for them to mark enemies for other soldiers.

Outlaws: Outlaws are the ones brought into this fight from the other side of the law, almost all of them former prisoners, though some have willingly joined the cause. The Outlaws are known for being slightly reckless when it comes to how they fight, choosing to wield Revolvers and a Explosive tipped crossbow, using trip-wires and Incendiary grenades to fight, always thinking that an under-handed move is a good move when it comes to fighting enemies. They are known for their deceptive abilities and under-handed ones. They employ trap based weapons, such as the Fire Bomb and Needle bombs, along with Pipe bombs and decoy grenades.

It's nothing massive yet, but I'll finish making this soon. The enemies will be revealed soon. ^^ I'm happy for idea's and comments to be posted.
