According to the ESRB, this game contains: Violence
Parents will want to steer little ones away from Silent Line: Armored Core because the control scheme is more complex than most children can handle, and the difficulty is harsh. The strategy involved in customization is better aimed at teens, in any case. There are no sexual situations, no questionable language and no explicit violence.
Multiplayer maniacs will love that the ability to daisy-chain four PlayStation 2's (along with four TVs, four i-Link cables and four copies of the game) is still in effect. Better take advantage of it now—newer model PlayStation 2s won't have the required i-Link port any longer.
Armored Core fans will have probably finished the game by the time this review is published, but I'll say that Silent Line: Armored Core has the toughest difficulty curve I've seen in the series to date. You basically know what to expect, but prepared for bigger challenges and smaller payoffs. Armored Core 3 save data is transferable to Silent Line.
Deaf and Hard of Hearing gamers can enjoy full accessibility. The game features full text throughout, and there are no significant auditory cues.
