What do you do in Eclipse Phase

In my campaign setting ( I use the core rulebook’s default campaign setting ) every player character is a “sentinel,” an agent-on-call (or potential recruit) for a shadowy network known as “Firewall.” Firewall is dedicated to counteracting “existential risks”—threats to the existence of transhumanity. These risks include biowar plagues, nanotech swarm outbreaks, nuclear proliferation, terrorists with WMDs, net-breaking computer attacks, rogue AIs, alien encounters, and so on. Firewall isn’t content to simply counteract these threats as they arise, of course, so characters may also be sent on information-gathering missions or to put in place pre-emptive or failsafe measures. Characters may be tasked to investigate seemingly innocuous people and places (who turn out not to be), make deals with shady criminal networks (who turn out not to be trustworthy), or travel through a Pandora gate wormhole to analyze the relics of some alien ruin (and see if the threat that killed them is still real). Sentinels are recruited from every faction of transhumanity; those who aren’t ideologically loyal to the cause are hired as mercenaries. These campaigns tend to mix a bit of mystery and investigation with fierce bouts of action and combat, also stirring in a nice dose of awe and horror.
