5th Cell's Xbox Live Arcade cover-based shooter Hybrid is having a rough launch, as the game has been pulled from Xbox Live Marketplace thanks to server issues. Since the game is an online multiplayer title with no single player mode, there was no other option if servers weren't active.
According to creative director Jeremiah Slaczka, "We are working with Microsoft to fix these server issues. Many people from both 5th Cell and MS are working together to sort the problem out. We are making progress, but it will take time unfortunately. Sorry for the inconvenience, however we don't foresee this problem to continue once it's fixed."
