There are currently three "core sets":
• Autobot Core Set
• A Rising Darkness
• War on Cybertron
There are also two "expansions":
• Infiltration Protocol
• Dawn of the Dinobots
The core sets can be played by themselves, while the expansions require at least one of the core sets. Of course, all of them can also be used together!
Additionally, each set has an associated "Bonus Pack". These were originally included with pre-orders, but can still be purchased after the fact.
All sets are available at
Renegade Game Studios's store, or on
their Amazon store.
