Greater Than Games slipped in an announcement for a Sentinels of the Multiverse roleplaying game in a large post about the company’s Gen Con plans. The company, primarily known for the Sentinels property, will have demos of the roleplaying game “a few times” during Gen Con 2015. The Sentinels game is described as an “upcoming RPG”. Players attending a scheduled two-hour demo of the RPG also receive a $2 coupon good at the GTG booth (2143).
