''Under Defeat'' is a 2005 vertical-scrolling shoot 'em up developed by [[G.rev]] for the Sega NAOMI arcade board.

The game is set in an alternate history WWII where two powers, the Empire and the Union are at war. You play as two German helicopter pilots in service to the Empire.

== Gameplay Overview ==
''Under Defeat'' is a vertical, two-button shooter. Your helicopter has two weapons: a primary shot, and an Option. The primary shot consists of two anti-air vulcans and a center vulcan that can target both air and ground targets. The Option passively charges when you aren't shooting. Once fully charged, pressing the fire button will release it.

Both the primary shot and the Option can be aimed by moving left and right. Holding fire locks your aim. The game features two aiming styles, Normal and Reverse. With Normal, your helicopter aims in the direction of your movement, and with Reverse, your helicopter aims in the direction opposite to your movement.

=== Controls ===
* '''A:''' Shoot / Release charged option
* '''B:''' Bomb

=== Ships ===
NOTE: The original arcade and Dreamcast versions only include the VKL 5.03.
{| class="wikitable" style="text-align: center"
|-
! Name !! Desc
|-
| '''VKL 5.03''' || Fires two streams of bullets directly forward. Option must be charged.
|-
| '''VKL 7.04''' || Fires two streams of bullets in a wider angle. No Option; the Option projectile is included with your primary shot.
|-
| '''VKL 6.02''' || Fires two homing rockets. Option must be charged.
|}

=== Options ===
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.

=== Bombs ===
The player can hold up to 6 bombs at once. Bombs damage everything on screen and render the player invulnerable for a short period of time.

== System Mechanics ==

=== Rank ===
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 how you are performing. 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. These are the base rank values for each stage:

{| class="wikitable" style="text-align: center"
|-
! Stage !! Loop 1 !! Loop 2
|-
| '''1''' || 0 || 19
|-
| '''2''' || 2 || 22
|-
| '''3''' || 3 || 23
|-
| '''4''' || 5 || 26
|-
| '''5''' || 8 || 28
|-
|}

Rank primarily affects enemy fire rate and bullet speed. This is especially pronounced on the second loop, where base rank is dramatically increased. When practicing stages, it is advisable to set the rank offset to +10 to simulate the worst-case scenario.

=== Scoring ===
Enemies destroyed by the Option grant double the points, meaning that enemies with high score values are a priority target. Picking up the same type of option grants a flat 5000. Tick points are gained by shooting both destructible and indestructible objects. You also receive the following bonuses at the end of each stage:

* Skill Assessment - Proportional to Contribution Percentage. Doubled if Contribution is 100%, doubled at 1 life, and tripled at 0 lives.
* 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.

=== Contribution ===
Your Contribution Percentage is the percentage of "contribution targets" that were destroyed during the stage. Many high-health tanks and turrets are contribution targets, as are certain background elements such as the howitzers in stage 1 or the ship antennae in stage 2. Random zako tanks can also spawn as contribution targets, denoted by striped paint or darker coloration.

There are also a handful of easter egg contribution targets that are easy to miss:
* Near the end of stage 1, a VIP car will drive out of the building by the edge of the water.
* In stage 2, during the boss battleship fight, there are two blue airplanes perched on the stern of the ship.
* Near the end of stage 3, a harmless lone vehicle will drive down the road before the exploding bridge.

=== Loops ===
In order to reach the second loop, one must clear the game with an average Contribution Percentage of >95%. The second loop is a mirrored version of the first loop featuring alternate environments. Since base rank starts at +19, enemies fire more often and bullets are faster. Some enemies have different behaviors (e.g. the towers in 2-1 aim instead of firing straight forward), and others spawn revenge bullets on death.

== Strategy ==
<div style='text-align: center;'>
''See [[(Template Page)/Strategy]] for '''stage maps''', '''enemy and boss descriptions''', '''walkthroughs''', and '''advanced play strategies'''.''
</div>
----
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. If you route correctly, micro-dodging is rarely a necessity.

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.

== Version Differences ==
The game was ported to the Dreamcast a year after its initial arcade release. The Dreamcast port is identical to the arcade version. In 2012, ''Under Defeat HD'' was released for PS3 and Xbox 360, featuring a 16:9 mode and updated graphics. Yet another revision, ''Under Defeat HD+'' is available on most modern platforms.

HD/HD+ has some extra features, including:
* Two extra helicopters
* New Order Mode, a 16:9 mode
* Arranged New Order Mode
* Arranged soundtracks
* Rank/Contribution display
* Twin stick support

In addition to new features, there appear to be a few gameplay differences between the arcade and HD versions:
* Enemies seem to fire faster and more often in the original (needs confirmation)
* There are some bugs/unintentional changes, like the ability to shoot the stage 2 boss while it is offscreen.
* HD suffers from slowdown that isn't present in the original (fixed in HD+)

== Trivia ==
* The cows at the beginning of stage 1 are possibly a reference to the background cows that appear in every Yagawa shoot 'em up (Battle Garegga, Ibara, etc.)
* ''Under Defeat'' was one of the last games released on the Sega Dreamcast. The last five games released on the platform were all shoot 'em ups, the others being ''Trizeal'', ''Radirgy'', ''Triggerheart Exelica'', and ''Karous''.
