Mission objectives are the name of the game. You will be sent from sector to sector accomplishing simple tasks and fending off roving squads of enemy Frames. Periodically you are asked to clear areas of the enemy Frames while protecting the inhabitants of the nearby buildings or destroying single obstructions like gates and the like. Confrontations with other Frames require you to destroy them with as few human casualties as possible. This usually means diverting their attention and luring them into less populated areas. At the end of each mission, you are graded on the number of civilian causalities and the time it took you to destroy the enemy Frames. The objectives can repeat unfortunately, but the outcome of each mission has an impact on the direction the overall story will take.
