From introduction: Test Facility 3188 is a short, introductory adventure, which was originally written to playtest the combat rules developed for use with Cthulhu Rising. The adventure is designed for up to six players, running a mix of corporate soldiers and other base personnel in the employ of the Japanese megacorporation Motokatsu-Kyono Combine (MKC). Keepers should feel free to substitute another mega-corporation for MKC if they so wish. It would be advantageous if someone in the group played a pilot and someone a computer specialist. Some examples of possible character types are provided in Appendix B at the end of the adventure. The group shouldn’t be too heavily armed, although starting weapons and equipment is down to individual Keeper discretion.
