Take a ride through an intergalactic journey where you slide, stack, and ignite your blocks to blast away the world-ending Meteos. Only you can stop them from falling and crushing your planet! Master combo links and power-ups to challenge your friends in intense multiplayer sessions.
Puzzle games don't get any better than Meteos Wars, where the story, situation, and environments formulate an explosive adventure."
Survive! Assimilate! Evolve!
In PowerUp Forever you have to grow to survive and to grow you must destroy! Hunt and defeat enemy Guardians to harvest their glowing energy cores, gaining power to grow your ship and expand your weaponry. As you evolve you attract the attentions of ever-larger enemies, and your fight for survival goes on.
