Steambirds Alliance is a new, and unusual, title in development from Spryfox. The game sounds like very little else out there in the fact that it will be free-to-play, support up to 60 players in a game, and it's a co-op focused bullet-hell shooter. Like, you'll usually get games that have maybe one or two of those elements thrown together, but not all of them. They're also saying it's got some MMORPG elements included along with a heavy dose of customization.
The overall theme of the game is a battle between birds and cats. You and up to 60 other players try to take down the "evil feline lord, Meowza" along with "his cranky kitty minions."
Steambirds Alliance is a massively-cooperative bullet-hell shooter! Fly with dozens of your feathered friends in an open world full of cruel cat bosses and endless waves of deadly bullets. Experience hundreds of unique enemies, a wide variety of secret missions, and many distinct plane types for you to unlock and master. Team up with your fellow birds to end the reign of Meowza, the evil cat overlord.
