What is it with aliens all wanting to come down and take over Earth? Can't they just go find some other planet to take over? I mean, really now. But invade they must, I guess. Thankfully, the Earth is ready to defend itself. At least, in Wolfstar Heroes the Earth has the ability to defend itself. The game is a strategic card game for 2-4 players and they're up on Kickstarter now.
In the game, you are either in charge of invading the Earth, or protecting it from Invasion. Players have their hand of cards from which they play energy Source cards that are then used to warp their ships around from deep space into the battle zones, or to deploy their defensive forces and call forth the various heroes available to them.
The campaign's a bit more than 1/2 funded and still has 26 days left to go.
