In 2000, Working Designs translated, made significant alterations to, and published the game for the PlayStation in North America.

Crawling and dashing allows the player to run up walls and along ceilings which acts as both an evasive and defensive technique and also as a means to reach hidden or seemingly unreachable areas.

[8] Additional weapons/magic known as "parasites",[8] such as "Surosa" (single shots), "Cavitas" (homing blasts) and "Grattoni" (a powerful laser) can be purchased with coins from the Hare Wares vendor at certain points in the game.

Most of the initial options are also locked in this version, and can only be modified by completing the game's five paths, upon which a special bonus feature is also unlocked.

Shyna's purpose is to track down and repair Edo to undo the damage that has been done and unite the two opposed types of beings that were created.

Due to the polar nature of these attributes, Armageddon was split into two individual entities known as Medigo and Hal, respectively the Silhouette and Mirage leaders.

Gehena then notifies Shyna that all Silhouette and Mirage lifeforms will be located, identified, processed and returned to their original selves.

[17][13] At the time the developer was shifting their focus to the Nintendo 64 and PlayStation, and announced that Silhouette Mirage would be their final game for the Sega Saturn.

[19] The gameplay mechanic of the player's power dropping if the spirit gauge falls was added near the end of development, and was based on a system Treasure used in Guardian Heroes (1996).

[20] Treasure re-used the dual attribute damage mechanic of Silhouette Mirage in their shoot 'em up game Ikaruga (2001).

[2] Treasure handled the port completely in house with a small team, including the difficult adaption of the 2D view into the PlayStation format.

[25][26] For the PlayStation version, the soundtrack was trimmed with the training music being replaced and a few minor background elements were simplified or removed.

[28] American publisher Working Designs localized the PlayStation version for North America and made further alterations.

[15] There are also secrets such as a debug mode, more options, and "Super Core Fighter 2",[27] a two player mini-game battle between Shyna and Zohar.

[29] Next Generation noted that the release of Silhouette Mirage showcased that Treasure was continuing to innovate within the bounds of an outdated video game genre.

[44] Greg Orlando reviewed the game for Next Generation, and stated that "Befuddled baseball player Richie Ashburn once quipped, 'I don't know what it is, but I know I've never seen it before.'

"[42] IGN praised "revolutionary new play mechanics and an insane amount of depth" and said that "it does push the 2D power of the PS to the max".

[12] GameSpot's review focused on the differences between the Saturn and PlayStation releases, mentioning the "inflated weapon cost" and the mechanic involving draining enemies' spirits, which they stated is "the biggest flaw in the game".

They went as far as to recommend importing the original Saturn release because "a perfectly fun game is now an unrewarding chore overwrought with tedium".
