Alright, I'll do my best.
So we're starting up the game with 4 players as Survivor-level characters (I really prefer playing Norms, but we wanted this campaign to last a while so we decided to go for durable characters), core book only. We were playing in a traditional, end-of-civilization style setting, and while our ZM never gave us the particulars he basically had us going against two types of zombies: smarts and brutes.
Smarts were fairly generic, slow, head weak-spot, spread zombification through bites, average strength and durability Romero-style zombies, but had good senses (particularly hearing) and were intelligent (just looking through the book and from memory, I'd say the ZM gave them Animal Cunning and Teamwork), and there were a fuck-ton of them.
Brutes were pretty much the opposite. They probably had Quick Dead, Leaping, Climbing, Strong Like a Bull, Claws, and a motherfucking heart weak spot, but were dumb as shit and could be avoided unless there were smarts around to point you out to them. There also weren't as many of them (basically a rare mutation of the disease caused it, fairly typical stuff). We were starting off in the ruins of a city bombed to hell by the military and gangs of other survivors, and from there he basically ran a sandbox for us and just let us have fun.
The other three players made characters with pretty good generalist spreads, lots of handgun, rifles, stealth, survival, that sort of stuff.
I, on the other hand, decided to play Reginald "Ragin' Reggie" Dempsey, an alcoholic ex-slum-fighter-then-junior-karate-class-instructor-now-zombie-apocalypse-survivor who wanted to, for once and now that it was the end of the world, feel like he was making a difference and help people the only way he knew how: by hitting stuff really hard.
