From publisher blurb:
A war-torn world hangs in the balance! The corrupt government of Telis is crumbling under the weight of rebellion, and they've hired mercenaries to help turn the tide. In turn, the mercenaries ask for the PCs’ help. They’re tasked with a seemingly simple job: blow up a bridge. But this isn't just any bridge. It's a direct route to the capital for the rebel forces, and a matter of life and death for the mercenaries. The adventurers are in a race against time as they contend with intense enemy fire and a volatile, unforgiving explosive before the mercenaries are overwhelmed. Failure means not only the loss of a mercenary company, but possibly an end to the heroes’ adventures at the bottom of a yawning gorge.
The Bridge is a short science fiction adventure using RPGs using 2D6 engine and rules such as Cepheus Engine and the Original Science Fiction Roleplaying Game. Other systems are easily adapted.
