Rank 52 follows 
Rank 51, and requires 14 out of 17 Missions to rank up to 
Rank 53. There is no researcher unlocked at this rank.
Tips[]
This rank is slow to begin, as missions #1 (600 Cards) and #3 (which requires 5 SS Bullets) are extremely challenging first-up. This leaves just one open mission slot to complete the other more achievable missions (and earn cards) until missions #1 or #3 can be completed, which may be after missions #8 or #9.
Once you have completed mission #7, avoid spending science in this rank if possible, as Rank 53 starts with a Spend 11,000 Science mission.
