Games in which the player shoots things to progress, usually with a variety of guns, and other times with bows and arrows.

Typically shoot em' up games where the emphasis is dodging a large number of bullets on the screen at once. Bullets form dense patterns on the screen that require precise controls to avoid.

Near infinitely replayable games that usually feature, random generation, perma-death, and brutal difficulty. 

Similar to roguelike games but generally with simpler or more forgiving rules & mechanics.
