Town of the Dead ZombieDefence! Wave based horde minigame

You (and other players) have crashed your safety semi in a small town. There are zombies everywhere and you are not allowed in the quarantined area. Lucky for you, all you have to do is, of course, turn on the power. Find out how to power the town so you can obtain access to your only spark of hope, the supermarket. Have fun playing and please give me a diamond if you like it! I also look over suggestions.

Help:
When you start out you may be in creative, simply double tap the space bar and fall onto the trip-wire platform and you will start at the spawn in adventure mode
Exit the room you spawn in through the doors once you grab the items in your chest and wait for the zombies to come!
Remember to make sure your game mode is on Easy, Normal, or Hard.
Play fair to enjoy the game.

Missions:
Go to the generators and switch the power on by finding the switch.
Search the map for what the generator does
Survive as long as you can WITHOUT dying
Once you die see who has more golden nuggets
Place 4 beacons in the "corners" of the map
Attempt to reach 500 kills
