1. Exit to Leisure Park and approach the clock tower to trigger a cutscene.

2. Hordes of zombies are in a cave beneath the tower.

3. The generator is found here.

4. Return to Isabela and let her know you found the generator.

5. Give Isabela any Queens you have. Select the Queen in your inventory, approach Isabela and press "B" for "Give."

6. You'll need to give Isabela a total of ten Queens. Here's an easy way to get them fast. Run the short distance from the hideout to Seon's grocery. Use this door to access the Maintenance Tunnels. (This is also a good spot to ambush Special Forces -- note all the bodies on the floor.)

7. Head down to the garage and get in this truck.

8. Ride around the immediate area and flatten all the zombies. Be sure not to venture outside this immediate zone or else the zombies will respawn and any Queens you've unleashed will disappear.

9. Exit the truck once the area is safe. If you followed my earlier suggestion, you'll have some Nectar with you. Drink it and any Queens in the area will fly to you.

10. You'll need to make several runs to give Isabela all 10 Queens. Her motorcycle just outside Seon's makes it easy to speed past the Special Forces.

11. Once Isabela has all 10 Queens, this cutscene plays.

12. In addition to synthesizing the vaccine for Frank, Isabella has created a new perfume for herself that repels the zombies. Frank hopes that this new perfume will allow them to walk through the zombie horde beneath the clock tower.

13. Enter the cave beneath the clock tower and save your game.

14. Hold Isabela's hand and you'll be protected by her perfume. Head to the circular gate ahead/left.

15. Press "B" and Isabela open's the grate.

16. Fend off the zombies while Isabella crawls through the grate and opens the gate.

17. Hold Isabela's hand and climb this block to find a Pick Ax if you need a weapon.

18. As you continue through the cave, you can go as quickly as you like, just make sure not to spin around, as you'll lose your grip on Isabela. Her perfume is the only thing stopping certain zombie death.

19. Open this door to load the next zone.

20. Continue holding Isabela's hand then climb over the rocks ahead/left.

21. Run the gauntlet to this next grate. Again, open it and Isabela will open the gate on the right.

22. Special Ops machine guns work well to fend off the zombies while you wait for Isabela.

23. Run down the corridor to view this cutscene. Isabela's perfume is beginning to fade, and you'll need to carry her so its scent can cover you both.

24. After the cutscene, you'll have a chance to save your game here at this block. Ready a weapon then jump down.

25. Clear a safe area around the block then carry Isabela to the left of the gate ahead.

26. Ascend the nearby stairs then pull this lever to raise the gates below.

27. There are three gates that have been raised. My preference is to avoid the guards by sneaking through this opening on the right. Note the apples ahead/left.

28. Find this Jeep a short distance on the right. Get in quickly to avoid the zombies.

29. This cutscene plays. It's you and Isabela against - a tank!

30. This shooting match is your next boss battle. Aim for the headlights and see flames shoot forth as the tank's health bar diminishes.

31. Periodically a laser sight will pop up from the tank. If you shoot it, the laser sight will simply descend back into the tank. Otherwise, the laser turns red as the tank locks onto you, and you will take damage. I found it best to focus on offense and keep aiming for the headlights.

32. I have the same advice for these mini-choppers. If you keep firing at the tank's headlights, you'll diminish its health faster, and chances are you take out a large number of the choppers as they cross your fire.

33. Deplete the tank's health and this cutscene plays. Time for your next boss, the military commander seen earlier in the mall.

34. Brock is your final boss. You'll fight him on top of his tank. The best strategy is to pummel him with special moves while he's vulnerable, which he'll be as he moves from the turret to the lower level of the tank. Stay off the turret to lure him down.

35. My favorite move for this is the Double Lariat. Hold down the left stick while pressing "X".

36. You want to avoid Brock getting you in this head lock. Rock the left stick back and forth to work yourself free when this happens.

37. Deplete Brock's health and this cutscene plays. Congratulations, you are about to witness the "True Ending."

38. After the final credits you'll get the True Ending text. Frank escapes, the world learns of what actually happened...but the people really don't pay much attention. Congratulations, you've now reached the end of the story and unlocked Infinity Mode. Game Over.
