Warning Forever/Getting Started

The premise of the game is to fight a constant stream of bosses. The gameplay is broken into stages; each stage is a single boss battle. To progress to the next stage, the boss must be completely destroyed within the time limit. The game starts with a default time limit of 180 seconds, with 30 seconds being gained for every boss defeated, and 20 seconds are lost every time the player is destroyed.

The following game types are also available:
 * 3 ships, where you have unlimited time but only three ships to attack with. An extre ship is obtained for destroying 100 parts.
 * Sudden death, where you have unlimited time but only 1 life during the course of the game.
 * 300 second countdown, where you have 300 seconds to defeat as many enemies as possible, with no time extension.
 * Custom, where you can configure the time limit and ships remaining to your liking (although you can't set both to unlimited.)

The main gameplay feature is how the bosses change from stage to stage. Based on how you fight a boss, the next boss will adapt itself to defend against your strategies, and prey on your weaknesses. For example, if you destroy the front part of the boss first, it will increase armor on the front. Likewise, if you are killed by a certain kind of weapon, but still defeat the boss, the next boss will probably have more of that weapon.
