There is nothing like the sensation of walking around in an Atlas in full battle, as you look down on the puny mechs below you and blow them to shreds. If you have a force feedback controller you are thrown about by the recoil of your own weapons and the impact of the enemy's. Targeting feels so good and so right as you automatically target what you aim at. Weapons sound so totally cool. You can hear the servos engaged when you turn or change speed.
Buildings explode and burn with a lovely light.
The AI seems much improved. Enemy mechs circle-strafe, jump and dodge among obstacles to avoid your fire. One mech, cowering in fear, jumped up and hid on top of a building. Even your death is beautiful. You are the song of a duke.
