''Under Defeat'' is a 2005 vertical-scrolling shoot 'em up developed by [[G.Rev]] for the Sega NAOMI arcade board. It was one of the last games released on the Sega Dreamcast.

Like G.Rev's other titles, the game uses a 3D engine.

== Gameplay Overview ==
The game features two aiming styles, Normal and Reverse. Normal aims in the direction of movement, and Reverse aims in the direction opposite to movement.

=== Controls ===
----
* '''A:''' Shoot
* '''A (Charged):''' The Option meter charges when you aren't shooting. Pressing A while fully charged to release your Option.
* '''B:''' Bomb

=== Characters / Ships / Styles ===
----
The original arcade game only includes one ship. The HD remake includes three others.

=== Items ===
----
This section describes any and all collectibles that you acquire in the game. An example being any '''Power Up items''' or '''Medals''' from ''[[Battle Garegga|Battle Garegga]]''. Include secret items such as extra lives as well.

=== Rank ===
----
The game features a rank system, but it has little bearing on strategy. Each stage has a base rank value. Your rank is calculated by adding the base value to a "rank offset", which can increase or decrease depending on your actions.

Rank offset increases at the end of each stage when no-missing and/or no-bombing the stage. Dying decreases the rank offset by 1. Because the game has no extends (score-based or otherwise), there is no reasonable way to mitigate rank, nor is it worth doing so.

Rank primarily affects the speed of enemy bullets. This is especially pronounced on the second loop, where base rank is dramatically increased.

When practicing stages, it is advisable to set rank offset to +10 in order to simulate the worst-case scenario.

=== Loops ===
----
The game features a second loop with increased difficulty. In order to reach the second loop, one must clear the game with an average Contribution Percentage of >95%

The base rank value of stage 2-1 is +19, which is double that of stage 1-5. The screen is tinted a different color, the stages are mirrored, and certain enemies have different behaviors.

=== Scoring ===
----
Enemies destroyed by the Option give double the points. You gain tick points by shooting both destructible and indestructible objects. You receive the following bonuses at the end of each stage:

* Skill Assessment - Contribution percentage multiplied by 200. The multiplier increases the less lives you have, meaning that optimal play involves dying twice on stage 1-1
* Fuel Conservation- The amount of time left on the boss timer multiplied by 1000.
* Ammo Conservation - The number of bombs left over at the end of a stage multiplied by 10000.

== Strategy ==
<div style='text-align: center;'>
''See [[(Template Page)/Strategy]] for '''stage maps''', '''enemy and boss descriptions''', '''walkthroughs''', and '''advanced play strategies'''.''
</div>
----

The game has a high degree of randomness. The Option type that the Option item spawns with is random.
Many of the bullet patterns are random, and the placement of contribution enemies is also random. Large enemies with high score values are priority targets.

== Version Differences ==
* Include information here about differences in a game between various versions. This includes regional differences, patch updates/bugfixes, and the like.

 There are three Option types. You start the game with the Vulcan and switch out your Option type by grabbing the Option item, which continuously cycles through the three types as it bounces around the screen. Picking up an Option item while your meter is on cooldown will automatically reset the cooldown, allowing you to charge again immediately.

-Target prioritization and screen management are highly important due to your narrow primary shot. If too many enemies clump up on screen, it's easy to get overwhelmed by intersecting bullet patterns. The game rarely requires micro-dodging if you route correctly.

 The Option is key to both scoring and survival. The Rocket does massive damage against bosses and can one-shot large groups of enemies, while the Vulcan and Cannon can supplement your DPS and/or cover blind spots. The Option is immune to bullets, but can be destroyed if it collides with an enemy.
