AC Athena X

AC Athena X

ATHENA X is a heavyweight two-legged AC equipped with a triple missile launcher, back magazine, rifle and the MOONLIGHT laser blade.


Siren tends to hop around the battlefield, either firing missiles from afar or chipping away continually at you with her rifle. If she manages to get close enough, she will slash away with her deadly MOONLIGHT blade, so it's best not to engage her in a blade fight. If you have Human PLUS, you can simply wait for her to land and then repeatedly fire MOONLIGHT blade waves at her until she's dead. But even if you don't have PLUS, she's still far from unbeatable.

Due to her being a heavyweight AC, she has rather limited mobility and thus is vulnerable to getting outmaneuvered. Because of this, it is relatively easy to get behind her and mow her down with powerful weapons of your own. Note that she does have decent defense as well so mediocre weapons won't be effective against her. Try to avoid her missiles and get around her rifle shots and she shouldn't be too difficult to beat.
