First for this achievement you need a minimum of
8.750 points to buy all the
doors, turn on
power and use all the
Lunar Landers (250 each). I show you the location of each Lunar Lander in one run from the spawn area in case you have never played this map before.
TipsIf you have a
Immolation Liquidation (Fire Sale) GobbleGum use this to get good weapons from the box to press
three times to place all three fire sales on the floor before picking them up. That way you have a 1 minute 30 second fire sale instead of 30 seconds.
Also the
Extra Credit GobbleGum can be useful as it give you 1250 points (2500 points when you have a 2x points drop active)
Another GobbleGum I'd recommend is the
Who's Keeping Score GobbleGum (Spawns a double points power up) This has two activations.
