Chromehounds

After completing the first training mission of the game, you can return to the main menu and choose which story arc to complete. Each arc has six missions and one training mission. Just complete those missions and training, with any rating. Each arc ranges from easy to hard, and will take time. Don’t get frustrated; patience is the key along with strategy. If one strategy doesn’t work, try another one. Adapt to the hound your using and learn how to use it properly.
