Welcome to the world of Samus Aran.
Attacks can only occur through the blue portals and the elevator shafts. The arrows next to the elevator shafts indicate to which area you will be moving. Be sure to check where you are attacking before you actually attack as some of the borders don't go where you want.
You have unlimited attacks and you can return to attack after transfer and after placement. You have 7 transfers.
Hordes bonuses are in effect.
Minumum bonus per turn is 5 and one bonus for every 5 territories held.
