Shattered Galaxy is an Online Massive Multiplayer wargame designed by Nexon in Korea and originally called Tactical Commanders and translated to English by the Nexon US Development team.
Alpha testing on Shattered Galaxy started in mid to late 1998, quickly followed by Beta testing in late 1999 and open Beta in early 2000 saw more than 100 players testing the game. Commonly called Phase One when the Beta testing opened saw such features as Player Made Factions and Phasing and Cloaking.
Shattered Galaxy went Gold in August 2001 when retailers started selling the boxed game on their shelves. Many beta test players pre-ordered the game through on-line retailers like Amazon and received special Abomination cards enabling usage of the Abom SG Unit in the game. Since then the Abom has been a sought-after enhanced Unit.
