Kinda self-explanatory.
I haven't played any of the Resident Evil games, so I'd have to say the Half-Life 2 zombies (regular, fast, poison and combine) where very nicely implemented.
Furthermore, I like the trash-talking zombies from Postal: Apocalypse Weekend.
And the blue zombies from Eternal Darkness, the ones that "sing"? Always fun to chop off their heads =]

My favorite zombie is Lord Raptor - you get to stick your ribcage through your opponents and turn them into a ball and slam dunk them

I'd like to see a zombie game implement zombies in the same way that the Dawn of the Dead remake did it.

On day (level) one there would be much fewer zombies around, but they're fresh and haven't rotted away too much so they're still pretty quick on their feet. As the story (game) progresses they get more rotten and slower but naturally, their numbers exponentially increase.

As far as my current favourite zombies in a game, I gotta go with Dead Rising. Even tho I didn't like the game very much, classic zombie shtick has always been about the masses for me.

I would have to go with the Half Life Headcrab Zombies (Not the crabs themselves, but the normal "Yabba my Icing!" zombie with a headcrab)

When Left 4 Dead comes out, those dudes.

"When Left 4 Dead comes out, those dudes."

Nemesis from Resident Evil

Necromorphs - Dead Space

I like the zombies in Dead Rising, even if I didn't like the game. Those zombies were how zombies should be: slow and stupid. If they run I can't think of them as zombies. I'm really looking forward to Left 4 Dead, but I'll never really think of the infected people in that game as zombies.

Im going to change my answer to Zombine from HL2: EP1 and EP2

I'm old school, and still have a special place in my heart for the slow, lumbering zombies from the Resident Evil of years past.

Left 4 Dead, fast and there are a lot of them
