This map has multitude of ways to complete it.
I will show you one of the easiers ways.

1.- buy an L-Car
2.- TETRIS, dont kill zombies untill the challenge is done. Before use the teleport kill zombies to win points.
3.- without buying nothing more go to FROGGER. Dont kill zombies. Waste your points to get a live only if you have 1 live and you have only 1 or 2 froggs to go. Before teleport waste all your ammo to get points.
4. Buy Double tap and ICR
5. PACMAN. At this point, you should be on round 4 or 5 so with doble tap and ICR will be so easy to kill panzers. Anyway try not to kill zombies untill you has the third panzer dead. If you want, before the teleportation, kill some zombies to get points.
6. Buy some peeks and go to Space invaders. Change the Lcar for the bazooka. Try to acumulate all zombies untill they stop spawning. Then start to shot to the invaders. Buttons to reactivate the reactors are up the stairs. The red invader has a moviment patron, learn it to kill him. Before teleporting be sure that you have 5000 points.
7. Buy a lmg and let the bazooka.
8. Go to 1943. Get the free max ammo and upgrade the shield of the ship if you need it. This challenge has sound alerts to know when there is gonna be an attack. Before teleport, get the free max ammo.
9. Use your money to buy some perks and pap your weapon but, dont on changing your weapons.
10. Go to Metal Slug. Next picture is a guide for the challenge.

11. Buy more perks.
12. Go to Donkey Kong. The easiest way to rise to the top is waiting for nukes or death machine. If you pass 5 minutes there, a help will spawn at start of the challenge
13. Try to unlock monkeys and shield on the bonus room. Buy everithing you can on the starting room.
14. KICK OFF pass the ball to your teamates (blue tshirt) if you try to advance before you pass to your teamates a defender will quit you the ball. The last teamates will pass you the ball and you must try to score. When you score a teleporter will spawn on the center point and all challenge will be completed.
