As you battle you'll earn cash and scientific research points which allow you to develop your mech, thus protecting your all-important commanders – if they die it's mission over. You can take chunks out of your opponents in a similar way, so you could slow them down or take out targeting systems depending on the nature of the task at hand. It's your call. And with a slew of bonus missions to complete, there's plenty of replay value too; this in addition to 30-plus hours of play. A final warning – some may baulk at the evil learning curve.
