In GG Classic we had zombies of a couple types: slow, fast running, fat, split, etc.
They were (are) not the best you can find around, of course, not "smart" and still a little buggy.
But the zombies we are seeing in GG Max, despite being better in some aspects, look of one kind only, like they are coming out of an old George Romero movie. Arms forward, and slow like having broken legs.
Can we hope in a wider variety of zombies, in the middle of the two?
