Due to this achievement/trophy requiring the player(s) to accumulate a large number of points, requiring at least 13500 points (7750 points for doors, 750 for the three Lunar Landers, and 5000 points for the Pack-a-Punch Machine, and additional costs for weapons and ammunition), players should go for headshots and melee kills for the maximum number of points and minimal use of ammunition, as well as taking time in rounds to rebuild barriers for additional points. Furthermore, training zombies will increase the players points as bullets will travel through multiple zombies, not only increasing points but conserving ammo as well.
Power-ups can prove less helpful or more helpful, depending on the situation. While the Nuke gives 400 points, it also takes away the potential points the player can earn from the zombies. Thus, it is best to be taken at the very end of the round, after killing all of the zombies, or picking it up right as it is about to time out. Insta-Kill will allow the player to conserve more ammo, however, the players will only get points for the kill, and not 10 points for every nonlethal hit. Whenever dropped, Double Points is an important drop, especially when it is the middle of the round. However, if there is only a few zombies left, then it would be best for the player to kill the remaining zombies, start the next round, and then pick-up it so the player will get the most time with the power-up.
Perk-a-Colas are very unhelpful for this achievement. While on solo Quick Revive can prove useful to inexperienced players, Juggernog will be a huge spending of points, and likely make it near impossible for the player to make up their points and then some for Pack-a-Punch.
- The name of the achievement/trophy is a reference to the Space Race, a mid-20th century competition between the United States of America and the Soviet Union for supremacy of space exploration.
