City Heights

I'm still working on Mortal Engines, but here's an idea for collaborating an RPG if anyone's interested.
I will start with setting and basic rules and will add more stuff, but I also would like it if others put stuff on as well.

New Cairo. City of mystery and excitement. Apparently. The mystery part's right, the NCPD drag up more unexplained corpses than Chicago, New York and Birmingham put together.
The police are a failing force in the citystate though, Voodoo Charlie and his criminal empire spread from Alexandria Docks to
Portland civic. That's not the only problem to contend with.
No-one's sure why the supernatural gravitates around New Cairo.
It just does. There are more super heroes and villains than you can count, Vampires, Werewolves even obscure stuff like an alien serial killer bearing a resemblance to Cthulu.
And the police have to try and keep track of it all. You have to pity them, really.

[Rules]
Here are the basics to surviving in the city. In certain instances, roll a number of D10s depending on your attribute and skill ratings (1-6). You only need one success (a 9 or 10) but there are modifiers, maybe your aim is put off by fog, a sudden movement, etc.
Here are the key attributes:
Strength, Agility, Wits, Purity and Intelligence.
Strength is key to a mighty character. Strength allows you to hurt people up close, smash down doors or move heavy objects.
Agility is linked to athletics, jumping etc.
Wits is used in ranged combat, to figure stuff out, use intuition and to avoid being ambushed.
Purity is your life force. Meta humans use this to activate key abilities, Norms use this to resist supernaturl attacks etc.
Intelligence is use to read ancient dialect, use a computer and so on.
All attributes can increase above 6 with XP, except Purity.

And here are the skills(add some if you like);
Athletics - Used for jumping and the like. Linked to ag.
Computer - Hacking, editing etc. Linked to int.
Drive - Using a vehicle. Linked to wits.
Investigate - Work out what happened. Linked to wits
Melee - Up close weapon use. Linked to str.
Movement - getting around. Includes swimming. Linked to ag.
Shooting - Using a ranged weapon. Linked to str.
Speak language - Speak or learn a new language. Linked to int.
Survival - living out doors. Linked to wits.
Unarmed combat - Who needs weapons? Linked to Str.

Character Creation:
I will try to make this as quick as pos:
1: Race
There are several races to choose from, here are some samples:
Human
The basic population. Humans make up about 72% of New Cairo
they don't have any special abilities other than colour vision.
Purity: If a human has a purity of 3+ then he can use magick.
Stat mods: Purity +1

Vampires
Vampires are undead. They don't consider themselves evil but they are prone to the blood urge, a force which drives them to gain plasmatic sustenance in any way possible, but the most satisfying is blood. Er, I think the posted comment by alderneyvamp pretty much covers their abilities (:)), but I have some additional to add.
Blood urge: Blood urge is the curse of the nosferatu. It forces them to take the blood of those around them. When in the presence of a group of humans or other non-undead they must roll purity to resist the Blood urge. If you suceed then your character acts perfectly normal but if s/he fails, you are forced to attack a person at random and attempt to suck their blood. Modifiers to roll: crowded area (-3) You have resisted for a year (+3).
Vampires may use magick.
Stat mods: +1 agility

Mummies
No-one is sure how the Mummies arrived in the big corpse. The main urban legend is that when building, workers desturbed an underwater mass tomb, awakening hundreds of the monsters. They are awe inspiring individuals,but have difficulty blending into a crowd (surprisingly, freeze dried corpses are noticable). Mummies are the only creatures whose Purity can go above 6.
Abilities:
Sand Hurricane: A Mummy can transform into a raging pillar of sand. Roll Purity to transform. Any body who is touched by the huricane takes a number of damage based on the Mummy's size + strength. The size of the hurricane is equal to a Mummy's purity.
Consume: This abilitie has two forms, Malicious and Vengeful. Used Maliciously, a Mummy drains the victim's life-force to heal themself. Roll Purity take the result from the subject's HP and add it to your own. Used Vengefully, a Mummy has spotted someone who has stolen one of it's canopic jars. Do not roll, just take your purity away from the subject instead.
Fear: Mummies are terrifying beings. Anyone who sees one in all his glory must roll Wits. If they fail they lose control and run at full pelt any direction as long as it's away.
Stat mods: +3 strength, +1 wits.
