''Geometry Wars: Retro Evolved 2 offers six gameplay modes: Deadline, Evolved, King, Pacifism, Waves and Sequence.
In King mode, you can only shoot when your ship is located inside of dynamically generated circles. The circles disappear, so you'll have venture around and locate another circle from which to renew your attack. An achievement in the prior title, Pacifism, is now a full gameplay mode. You must avoid shooting, so you kill enemies by leading them through gates, which will close after you pass through them. If you time it just right, the gates will explode at the opportune moment and take out a few enemy vessels. In Deadline mode, you're given three minutes and infinite lives to achieve the highest score that you possibly can.''
