It's not available in the US or Canada with a properly regioned account, but the demo is kind of good. I only say kind of because it doesn't include multiplayer or hound customisation which is the two things the game is being sold on.
Gameplay wise it is ok basic Mech combat, but something annoyed me a little. In Mechwarrior your commanding officer is on the battlefield in the most powerful Mech and he directs the squad from the front. This is logically correct because he is the most experienced pilot, but in Chromehounds, he is sitting in a C&C hound at the back. It just feels wrong because that isn't a job for someone with combat experience.
