From the campaign:
Legacy uses an interesting Line-of-Sight Combat system, making placement of your characters as important as which characters you play.
There are 3 types of cards, each broken into two categories.
Characters Cards: Heroes and Minions
Item Cards: Normal and Relic
Event Cards: Magical and Physical.
Void cards can be any type of the above mentioned cards, and can be retrieved from the Void using Void Points which you can gather during game play.
For beginners, the Game is easy to learn and has a fast pace to it.
For advanced card gamers, there is a rich level of complexity with the hero leveling system or Team Attacking!
