Delta Weapon


Delta Weapon
Dose is built up gradually when the Force device comes in contact with an enemy or enemy fire.

Dose Break

When the Dose meter reaches its maximum, the Force reaches a condition called Overdose, which both raises the player's score and enables the invocation of the Delta Weapon.

Delta Weapon

This weapon can be fired while in Overdose mode. It drains the Force device of its Dose, doing critical damage to all enemies on the screen in the process.


There are a total of seven stages in R-Type Delta, numbered in the game as 1st Contact,  2nd Contact, etc.

1st Contact "Lethal Weapon" (狂機)

1st Contact
Boss: Moritz G  
An unnamed Asian city, likely Japanese. One of the mid-bosses for this stage appears almost immediately, but its laser fires only in a straight line, making it not that great a threat.

2nd Contact "Deformation" (異形)

2nd Contact
Boss: Dust Nate Cocoon, Dust Nate Worm
A flooded energy reactor. This stage crawls with organic types of Bydo. The background music changes when the player submerges in or surfaces from the water.

3rd Contact "Gigantic Attack" (巨襲)

3rd Contact
Boss: Geitz 
A military base in the snow-capped mountains. In this level, rather than a giant space ship, the enormous four-legged Geitz chases from behind. The player has to fly through the space between its legs and finally assault the core at its top.

4th Contact "Invasion" (侵食)

4th Contact
Boss: Q.T. Cat  
Set in the space fortress Aegis in orbit of planet earth, this stage scrolls upward. In the latter half of the stage, the player has to navigate a maze of moving pillars. Also, inside the boss, Q.T. Cat, is the first generation R-9.

5th Contact "Evil" (邪悪)

5th Contact
Boss: Gondolan, Gommander, Green Inferno 
The interior of some mysterious organism. Throughout the stage, enemies from earlier se ries appear, and bosses from the original appear in succession. Later in the level, the player faces a difficult battle inside a spinning pipe. All sections of the stage are based on the original game.

6th Contact "Awakening" (覚醒)

6th Contact
Boss: R-9, Patrol Spinners (2),  Dobkeratops  
The headquarters of the R-fighter development project has suffered a fiece Bydo attack. Half-way through the level, the player's skills are again challenged as a Nozari creeps up from behind and other enemies rain down from above. The bosses included the infested R-9 and a resurrected Dobkeratops.

Last Contact "Life" (生命)

Last Contact
Boss: Bydo Core
An alternate dimension created by the Bydo Core. Human architecture and genetics are the theme of this stage. Once the membrane of the Bydo Core is destroyed, the Core steals the player's Force device, however it can be defeated using the Delta Weapon. Part of this stage makes another appearance as a hidden level in R-Type Final. 

Playstation Network

The game is available on the American Playstation Store for $5.99.
