Who here plays Urban Dead?
I do, and I currently have two characters running around the city. One is a 3rd level Corpse, and the other is a 5th level Firefighter.
It's a fun game that you only need to play once a day for 20 minutes. The best classes to start off with would be either Firefighter or Private. Doctor would be alright once you got the ropes, but it is a lot harder to level up.
For human characters, make sure to stay indoors before you run out of Action Points. Being stuck outside would not be hot when Zombies come munching on you. Most of the time Zombies don't look inside places unless it is a hospital, police station, or mall.
Uh... Have fun, I guess.
