It is clearly the same Final Boss as that of [[Radiant Silvergun]], the ‘Stone-Like object’. In RSG, the Stone-Like is the earth's ‘guardian’, which judges mankind to unfathomable standards: once humanity derails too much from them, it resets the world, wiping out everyone and allowing some human clones to start populating the earth again, in an endless loop. In ''Ikaruga'', the Final Boss does not have any explicit characterization, and while some believe it to have the same role as in its prequel, others think that it is entirely controlled and exploited by human beings

-Following the GameCube release of the game, a scoring competition was launched by the publisher (Infogrames, under the Atari label). Known as the ‘Ikaruga Net Ranking’ contest, it ran for about three months, during which players from all over the world could submit scores to a dedicated website. The legitimacy of the scores was ensured by the inclusion of a dedicated ‘Challenge’ mode on the GC version, which assigned a unique 12-digit code to every score achieved (on 1P Normal Arcade and Prototype modes): this code had to be entered on the website for the score to be submitted. The players with the five highest scores on each mode at the end of the contest received an official Atari trophy. After the official website went down, a few dedicated players managed to crack the code and implemented the feature on unofficial scoreboards hosted on the ‘Ikaruga.co.uk’ website, which remained the point of reference for the western community of ''Ikaruga'' for several years unitl its discontinuation.

 The Energy release mechanic can be briefly outlined with the following notes about individual laser behaviour and release behaviour as a whole:
-* the lasers are launched from each side of the ship (six on the left and six on the right for a full release), with their placement on the volley influencing the individual behaviour of some of them (for example, the upper lasers depart a bit earlier and generally tend to hit their target only after turning around on their path)
+* the lasers are launched from each side of the ship (six on the left and six on the right for a full release), with their placement on the volley informing their individual behaviour (e.g. the upper lasers depart a bit earlier and generally tend to hit their target only after turning around on their path)
 * upon releasing, each laser targets an enemy which is on-screen at that moment (if any). The release as a whole allots lasers to the various enemies according to their number and durability. If the release does not have the capacity to wipe out all the enemies, it tends to concentrate most/all of the lasers on portions of the screen and/or more durable enemies
-* assuming on-screen enemies of equal durability, the lasers select their target based on the combination of its ''proximity'' to the position of the release and the ''preferred path / screen-time'' of each laser in the volley. Timing-wise, when releasing with a surrounded ship, the enemies that are immediately below or beside the ship will generally be taken down first, followed by the ones which are in the front area and then those down below
+* given the general release behaviour above, the lasers select their target based on the combination of its ''proximity'' to the position of the release and the ''preferred path / screen-time'' of each laser in the volley. Timing-wise, when releasing with a surrounded ship and assuming foes of equal durability, the enemies that are immediately below or beside the ship will generally be taken down first, followed by the ones which are in the front area and then those down below
 * if a targeted enemy is taken down or goes off-screen before being reached, its targeting laser will redirect to another enemy (generally, if it was on-screen when the release was executed) or otherwise it will fly off
 * the lasers fly at a varying speed: they are slower when turning around and faster when going straight.

-It is important to note that the Energy release has no regard for chain integrity: the lasers' behaviour is independent from the enemies' colour an chain status. On some occasions, the chain can be preserved while releasing on both black and white enemies, but that only comes as a by-product of the general behaviour rules as briefly descripted above. Since these are deterministic rules with no randomness involved, every given release will produce a consistent outcome if the necessary conditions are met. On the other hand, very slight inaccuracies can alter the outcome of the release considerably.
