[MTF] Σ66 Sigma-66 "Sixteen Tons" #5331882
Game fan groupsENSCP FoundationMilsimGaming Community
Description
Sigma-66 started off on April 2, 2021 with a purchased map, five members, and a free gun system. The community grew steadily, eventually becoming one of the largest and most well known SCP milsims on the platform. The group also founded Apollyon Milsim, which donated assets and gave guidance to smaller groups in its circle. Although Sigma was hardly realistic, and there were much more immersive groups, the friendships made and the memories shared will last many of us a lifetime. Thank you all for participating. Group officially ceased on September 10, 2022
