Mass Effect: Terminus brings the Mass Effect universe to the tabletop with fast-paced skirmish action. Players command elite forces from nine different factions - the Human Systems Alliance, the Citadel Council, the Pirates of the Terminus Systems, the Asari Republics, the Turian Hierarchy, the Salarian Union, the Krogan Clans, the Quarian Migrant Fleet and the Geth.
The game contains a mix of nine different scenarios, further modified by seven different sets of environmental special rules to ensure that each game is completely different to the last.
Players can also link their games together with a deep narrative campaign system, allowing them to create their own stories in BioWare's rich, textured universe.
I would recommend using a mixture of Infinity and Warpath miniatures to create your forces, requiring minimal conversion to get them ready for the tabletop.
