Pulsar Game
Pulsar is a card video game using Stars as gameplay key elements.
... together, in other words it is a network of Stars, as a constellation is. Linked AMAS Stars combine their power to generate the attack.
They cannot die but they need to reload themselves to generate a new attack.
Defense Stars have Defense Points (DP). When a Star does not have enough DP to survive, it can either simply die, transform to powerful (yet weak) Stars or explode becoming a Black Hole! It depends on the type of star (red giant, blue giant, yellow dwarf, white dwarf...).
