You are inside a research facility powered by a reactor core underground in the Sahara desert. You can either be security, or TMS. If you’re security, you have to guard the core, check for suspicious activity, and help with core controls. Do not hesitate to kill a TMS agent. They are trying to destroy the core. If you are TMS, you sneak in the facility, kill guards and workers, and disrupt core controls so it can have a meltdown. You can either do this guns blazing, or stealthy and unseen.
