[Mean]

pawn Код:

if( sscanf( params, "u", pID ) )

"u" is for users.

pawn Код:

SetPlayerPos( pID, ZOMBIESPAWN );

Mind showing us ZOMBIESPAWN?

Also, you are giving player a weapon with no ammo... Like you didn't even give.
So change it to:

pawn Код:

GivePlayerWeapon( pID, 9, 1 ); // Gives player one chainsaw
