Main objective: Identify and destroy the colors as descibed in the level or trial's content. 

The first mode - Story: Try to complete the missions assigned to you, a Chromatic Soldier, by the Bureau. You may not like some of these, especially when you are ordered to genocide the native cells, but this is the Bureau. You will do as it wills.

The second mode - Endless: Travel to three different worlds and take part in the eternal (at least for now) missions unique of them. You can give up midway, and others will takeover, but something is watching over your progress. And it remembers.
