FIrst: probably you better use entitydistance for the ammo- and health-boxes to save some speed.
The other thing: I am not sure I I understood what you're after, I guess you want the zombies to have collision and gravity and all?
Well, as far as I see you are using the same number for Player and Zombies. In theory they should be handled the same way now, tho, you need to apply gravity to the zombies as you did it with the player, if you want this at all.
If you use the same number (2) for both, player and zombie, then you will not be able to define some special collision behaviour for the zombies. Furthermore, defining "Collisions Player,Zombie..." (that is 2,2) will force Blitz to check Collisions of Type 2 against themselves, eg: Zombie1 against Zombie2 and visa versa etc.
Maybe it's easier to use a diffrent type for the zombies.
