I'm actually been following the Cortex Command development for a while, but there comes a point when you have to say "no more". Last I played the game was, as Misery says, a broken mess. Never have I been so disappointed in a game developer than Data. This game had huge potential, but through lack of care over the 10 plus years of its development the game has kind of died, rotted away, been raised, died, rotted some more, raised again and now it's become some kind of undead shambling zombie, stumbling through its existence. The game should probably be laid to rest.
... having said that if you can get a free key or wait for a 75% steam sale there is still some fun to be had. Just don't expect anything close to resembling a finished product.
