Talk:Split Chamber/@comment-147.32.114.122-20131002112536

Go and farm tier 3 def missions, there is a 2.01% chance to get it!.. if you are lucky then you can get soon... Here're my calculations: this probability is based on a binomial distribution,and there's a formula for calculation the probability, image you made 50 runs of tier 3 def mission ( in one mission e.g. 3 waves and 50/3 = 16 mission runs ), the summed probability of getting a split chamber is 37,2%, so generally not that bad!..
