Space Invaders Infinity Gene

Title screen
Release date	2009
Developer	Taito
Publisher	Square Enix
Platforms	XBLA, PSN, iOS, Android

Space Invaders Infinity Gene is a Space Invaders game that focuses on the concepts of evolution, released on Microsoft's Xbox Live Arcade for the Xbox 360, Sony's PlayStation Network for the PlayStation 3 and the Android and iOS devices. The graphics are vector-based, and largely match the look and feel of the original game. As of 2017, Space Invaders Infinity Gene cannot be found/played on the app store since the release of iOS 11 which ended the era of 32-bit games.

The game opens with the following quote, hinting at the evolutionary themes of the game:

"It is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is the most adaptable to change." - Charles Darwin

The game is dedicated to "everyone who loves games, and Charles Darwin."

Gameplay

Players control a ship on the screen by dragging their finger around the screen. The player must avoid fire from the alien ships while destroying them with their own weapons. The well-known UFO now drops neurons that allow the player to upgrade their current weapon, until they are destroyed. Some levels scroll from top-to-bottom, adding walls that the player must avoid to the obstacles. Many levels feature one or more boss ships, labeled as "unexpected enemies" or "formidable enemies" ("huge enemies" in the iOS versions).  

A chain system rewards rapid destruction of enemy ships. Players earn an additional 0.1 multiplier for each chain achieved. 

Immediately after an enemy fires, their shots are briefly transparent and can be passed through. Moving through a transparent shot earns the user 3000 points. This maneuver is called a "Nagoya Attack."

Each stage records the high score, best chain, and Nagoya Attack achieved. After a stage is completed, points are accumulated into a "Gene" gauge that, when filled, triggers an "Evolution", which gives the player new selectable weapons (such as homing lasers or wave beams), new abilities (most notably, the ability to move vertically), bonus stages, and extra content in the main menu. Evolutions that are earned in later stages can be used when replaying earlier stages. Most stages have multiple features to be unlocked by a second, third, or even fourth completion. These unlockables range from new weapons and secret stages to extra lives and art galleries, each one an extension of the player's evolutionary tree.   

Other Features

In addition to the 38 primary levels, players can utilize "Music Mode" to generate a random level on the fly matching the length of the music. Due to limitations of the iOS API preventing access to the raw music data, it is not clear whether the levels are truly synchronized with the music.

A sound test and graphics gallery mode are unlockable via gameplay.

iOS 11

On September 19, 2017, with the release of iOS 11 for iPhone and iPad, Apple reported that they will be dropping support for 32 bit or unsupported apps. Many 32 bit games which also included Space Invaders Infinity Gene was pulled from the app store following that date. There is no reliable information when Space Invaders Infinity Gene may come back to Apple iOS devices later on.

Music

Music mode is unlocked as an evolution reward. It allows the player to import music into the game which will play during a level. It also uses that music to create a visualization that renders underneath the vector graphics for the game. In order to use this mode, an audio file, such as an MP3, must be on the storage device or hard drive of the console.

Challenge

The normal mode has several different minibosses. Most of them make appearances at scripted moments in the normal mode, but many of them show up randomly in later levels. The only exception is Nameless which appears in level 5-6 only. However, it can appear at the end of a level randomly in Challenge mode.

• Boomerang*
• Silver Hawk - Fires a large wave attack as well as four bullets from the ship in an x pattern.*
