I have a stategy. Actually two strategies.
1. YOU RUN AWAY FROM ZOMBIES, AND GO INTO ARROW RANGE ( iF ZOMBIES COME FROM BACK STUN THEM AND THHEN COME TO STRATEGY 2)
2. YOU RUN INSIDE THE GATE, AND STAND BY THE GATE WHEN YOUR IN IT. THEN KEEP STUNNING ZOMBIES COME OUT OF THE GATE SO YOUR STANDING IN THE OPEN GATE DOOR HIT THE STUNNED ZOMBIES, AND KEEP REPEATING THIS. (THIS DOES TAKE A WHILE, BUT ITS WORTH BEATING THE LEVEL. (IF ONE OF THESE STRATIGIES HELP + THIS COMMENT IS NOT - IT IT WON'T HURT MY FEELINGS, BUT TRY IT BEFORE YOU JUDGE IT.)
