Danmaku

Summary
Danmaku (弾幕, literally bullet curtain or curtain fire) is literally the ability to produce a great amount of projectiles at once, in order to overwhelm the target by the sheer number of shots. Some users also add complex patterns to make dodging additionally difficult.

Types

 * various different kinds of projectiles can be used
 * linear projectile trajectories or curving shots
 * one directional, multi-directional or omni-directional
 * from one origin point or multiple origin points

Limitations

 * use for extended periods of time might be exhausting
 * might be incapable of controlling the trajectory of each individual bullet or be limited to patterns
