Kokuga

Each stage has the player move through destroying other mechanical, tank-like, turret-like, and robotic enemies.

Most stages end with massive and varied boss battles.

Stages are separated into segments with large gates at the dividers--destroying all enemies before destroying the divider resorts in bonus shield repairs.

Destroying the gate without defeating all the enemies in that section merely results in all enemies therein being annihilated.

Kokuga differentiates itself from most other shooters in a variety of ways.

Rather than collecting power-ups, players already have 20 "cards" to utilize.

Of these 20 attack and support cards, four are randomly displayed on the touch-screen at a time and offer a variety of abilities, from an offensive laser ring around the player, to homing shots, to shield restoration and damage repairs.

Players cannot cycle through the cards, and in order to get new ones, at least one current card must be used.

In this way, the game offers an unusual strategy element to the shooter gameplay--careful and planned use of power-up cards over simply powering up as much as possible as soon as possible.

Also different is the level set-up.

There are three "final" stages at the corners of a triangular grid which make up the final stages.

The stages themselves are laid out somewhat like a keyboard labeled with letters A~L, and a player may start at any stage.

However, continuing through the game requires a player to select an adjacent stage from the completed first.

A final "game ending" stage can only be played once an adjacent stage has been completed.

In this way, players may play for as long or as short as they wish.

With games encompassing several stages, or just a couple.

Kokuga for Nintendo 3DS is currently worth €58.37 loose. Prices are based on real sales and update regularly on Gamevaro.

Kokuga has only a handful of tracked market sales, suggesting relative scarcity compared to more common Nintendo 3DS titles.

Loose means cartridge or disc only, CIB (complete in box) includes the original box and manual, and sealed means factory-sealed and never opened. These are tracked as separate market values because the price gap between them can be significant, especially for older releases.

The PAL version of Kokuga is currently worth €58.37 loose, versus €53.36 for NTSC-U. Regional price differences usually come down to print run size and regional collector demand.
